I was given a brand new lawnmower that was 3 years old and only ran once, couldn't get it to crank because of old gas, followed your instructions, literally took me 15 minutes from start to finish and it cranks every pull on the first try. 👍🏻🙏👍🏻🙏👍🏻🙏❤️🙏
High lawn mower lady, I am hoping you can help me. I am looking for what carburetor to buy for a Briggs and Stratton 190CC indeed CC professional professional series 600 Briggs and Stratton is no help And all my searching on the Internet does not does not help me find the correct carburetor to purchase. This is actually for a brute22" trimmer. The model number is BS1022H. Are you able to help me find the correct carburetor to purchase? Thank you very much
@@katkat1693 The model number of the trimmer won't help you. Find your engine model number: www.briggsandstratton.com/na/en_us/support/faqs/browse/engine-codes-model-numbers.html and plug that number into parts houses search engines to get your correct carburetor.
@@TheLawnmowerLady Thank you very much for that information and the website. Unfortunately I have looked all over this engine for some type of identifying number. I am unable to locate it Anywhere. I have torn this trimmer apart And tried to clean the carburetor Following your instructions. By the way they were very clear instructions and it was a great job in your video. I will try again To locate the model number. Unfortunately nobody at Briggs and Stratton Is available to get that information. Thank you again for your quick response and I will let you know What happens
I'm a 64 year old woman. Bought the lawn mower last year worked great won't start. Took a few things apart cleaned them. Then I had to come to your TH-cam video for help. I watched a few others but yours was more thorough and explained every part. I think taking off the top is a much better route than some of the others showed. Think that's my next weekend project. The weeds are overtaking my yard.
Thankyou maam your the first person I ve seen on the internet clean a plastic carb correctly I m a small engine mechanic in N.C they never take the main jet apart thankyou again for showing the proper way
I drill out the bottom main jet with a # 72 drill bit .025 works great , starts first pull ,,,,even the ones without the auto choke . Been working on mowers for over 50 years ,,,I'm a 74 year old machinist and I'm like you " Old School " !
I’ve fixed a lot of things with TH-cam videos, and yours is the best. No skipped steps, no dumb product placement, clear AF, and really good editing and production. I’m going to see if you have one on chainsaws after I mow my lawn
Best carb video so far. You are clear and concise. I especially like the fact that you show the whole process without all the chatter and filler. I'll definitely check your videos first. Great job.
I would like to take a moment to thank you so much for your how to step by step video. It was Christmas Eve 2022 and our lawn mower began losing power and stalling on sloping surfaces ran fine on even ground. I disambled the carbureator and found it full of water also found the breather hose not connected to the air filter. After performing all the steps in this video our lawn mower is back up and running and no longer losing power or stalling when mowing on a gradient/slope. Your video has saved us time, money and a whole of stress as we were about to give up and send mower for repair. Thanks agin so much!!!!!!
Wow! Fantastic video. I tried to repair my Briggs & Stratton pressure washer engine with no help or video. I did most of what she said (it turns out) BUT, I learned three critical things from this vid that I never would have found on my own. Great advice, great quality video, very clear and VERY Helpful. Started the machine on the first pull and it runs like a dream, after sitting dead for two years. Thank you, Lawnmower Lady!
Thank you, Lawnmower Lady! Every year, it's the same thing - my lawnmower won't start, so I pull out the carburetor, clean it out, then it starts right up. This year, I repeated the process, but it wouldn't start. I was scratching my head and after enough wasted time, I pretty much decided I was going to go buy a battery-powered lawnmower after work, that is, until your video popped up in my feed. I saw the problem at 8:00, the white donut ring had popped out of my carburetor when I had removed it from the lawnmower. I had no idea it had gone missing (and didn't even know to look for it as everything looked ok inside there once I popped the fuel stack back in). I went back out to the garage and found it camouflaged with lots of junk on the floor, put it back in, and the lawnmower started right up! Thank you for your detailed instructions, just enough info to get right to it and point out all of the important parts, but not too much like some others can do. I especially appreciate that you showed how to pull the carb off of the lawnmower (I had figured that out on my own previously, but it helps to see the whole process - and...pulling off the cover is super simple and makes removing the carb easier) - other folks just start their videos after they've pulled the carb out. Looks like the ole' gas-powered lawnmower will survive another summer.
Thanks! Your comments are music to my ears. I'm so glad I could help. Some of those have a black donut ring collar,, and those are nearly impossible to find in the dark recesses of the garage. Cheers!
I watched half a dozen of these videos on this carburetor cleaning, and this one was a stand out. She walks you through the relatively easy (once she shows how) method to remove the linkages from the unit (I messed it up the first time I tried doing the clean). Further she did another breakdown of the nylon stack which no other video showed and all I can say after doing this, was able to finally get my lawnmower to run. Don't waste your time on the other videos; start and end with this one. Nicely done "Lawnmower Lady"!
Very nice work! Clear and concise. The only thing I would have done differently is drained the tank and started with fresh fuel, since there was so much water in the carb previously and you were not sure where it came from. I definite learned a couple of things from this video! Liked and subbed!
Thankyou.. been working on small engines for 40yrs and I just couldn't figure out this plastic carb.. you made it easy to figure out how to clean it and now it works like new again! You ROCK!
Glad it helped. As much hate as there is out there for these carbs, they really are pretty simple. They are more prone to getting clogged up with debris that gets sucked into the carb throat. I appreciate you watching. Cheers!
Wow! Even my favorite small engine repair channel did not show that you could separate the atomizer out to clean it. Glad I stumbled across your video.
Excellent video. I have a Hyper Tough with one of these plastic carburetors. I did remove, disassemble, and clean the carburetor, but at the time didn't know about snapping the one section out. So, I will do that at the end of the season. I actually like these plastic carburetors and think they are pretty simple compared to others I have cleaned. Very well explained and filmed video. Thank you.
Thanks a bunch, ma'am! My mower is back up and running, saving me both the diagnostic fee and the labor, which was going to be more than my mower was even worth at this point. You're amazing, and the instructions were clear enough my child could have done this. Really appreciate it!
Just wanted to say Thank You for ur videos! I've never had anyone to help teach me how to do repairs on my equipment before so when I came across ur videos, it was a tremendous help! You have the best details and information, where other videos just rush thru... I was successfully able to do the repair I needed to get little mower going again! Thanks a bunch! Hope u stay blessed and happy!
This is the best video on cleaning the plastic carb, the only thing I would do is I would drain the tank because of how much water was in the carb. Please keep doing these videos.
Replaced the entire filter box & primer assembly & it started up ran for about 30 sec & cut off. Definitely thankful for your disassembly vid of this carb cause I suspect water is trapped in carb preventing fuel from reaching combustion chamber. Great vid. Thanks a bunch.
Thank you so much for this video!! First time working on this type of carb. Your delivery on instructions is clear and precise. I was able to repair my son’s lawnmower.
I just came down here to thank you for making and posting this video. I was researching my carburetor issue on my mower when I found iy. Now that I liked and subscribed, I have only one question left to ask: can you adopt me? You are the coolest grandma ever. I wish, I’d had somebody like you in my life growing up. I bet, I could pick up a lot just watching you loitering around your workbench. Thank you again!
I hate to say it, I saw a woman, and thought, oh no here we go. But you completely made me have to rethink my attitude. Your very thorough and clear. ❤️ thank you for a great video.
Great video as always! Engines with the plastic carb has a tendency to surge due to the small jet. According to Briggs they run very lean due to emission regulations in different states. They surge a lot here in Europe too. A tip here for all if your carb is clean and it still surges - is to upgrade to a bigger jet - Briggs part no 596524. That often fixes the problem. Personally I prefer to old carbs where you could adjust the mixture. :) Cheers!
just think abt this for a minute.. briggs uses the same exact carb , with same exact jets, throat size, ect for 4.5. 5. 5. 5 , 5.75 hp mowers... how are they achieving this wide difference in hp, with the same carb? I dont think they are., I think its a scam. most of the new generation has never used a real 5 hp engine so they dont realize the difference.. they jets are way too small to pass enough fuel for the hp they claim., also the throat of the carb is restricted by a plastic ring .. why did they do this? I think its to restrict air. the engine operates under vacuum, and can only pull so much fuel out of the jets under a specific vacuum and volume. another problem with the plastic carb design is the 90 degree bend in the white jet chamber. anytime a fluid or vapor has to make a 90 degree turn, it causes resistance by a factor of 5. example.. if you put a 90 degree fitting in a garden hose, it is equal to 5 extra feet of hose that the water has to travel thru.. its amazing that these mowers run at All.
Interesting & thanks for the part number. Mine's what I call 'hunting' quite badly.. think that's the same thing as 'surging'.. Might give the different jet a go if cleaning the plug doesn't help. EDIT nice one - you set me on the right path to getting it sorted, using the old original jet (totally blocked, but once cleaned, turned out to be way bigger than the jet that came with the replacement carb I ordered off Ebay)
If jets are not available, you can use a .020" pin vise or drill bit, whatever you like to call it & drill the jet out. I have had a 100% success rate so far.
@@jackwarren3882 A video by Steve's Small Engine Saloon also mentions drilling out the jet to prevent it from clogging again. I noticed the "High Speed Steel Micro Drill Bit Set, 30 Piece" for $3 from Harbor Frieght has a bit this size. It's .5mm (same as .020"). But I'm wondering instead if just installing a fuel filter will also prevent it?
Thanks for the instructional video. Just picked up a Craftsman mower someone was throwing out. Cleaned the carburetor with your video direction and runs like a champ! Thanks again.
This is the most detailed video that I have found on this subject. Now I know where that large black O ring came from that fell out when I pulled the carb off. And i didn't know that the white hard plastic O ring snaps in on top of it. Thanks.
Here is an idea that helped me. I added an inline round disc fuel filter between the tank and carb. The type with the 150 micron metal mesh in it. Doing that has helped prevent the clogged carb jet issue. These are great mower engines.
Köszönöm a precíz bemutatást! Dadogva járás után leállt; gondoltam kipucolom a karburátort, de ilyet még nem szedtem szét . . . Szerencse, hogy rátaláltam - bár majd' az összes szerszámom megvan hozzá - biztosan eltartott volna fél napig amire megcsinálom! Külön köszönet a viszonylag (kis műszaki tudással!) "érthető", MAGYARRA állítható automatikus fordítást ;-) Viszem a szervizbe . . .!
Thanks for the detailed directions on the rebuild. I spent all day trying to put this thing back together. I watched your video and you mentioned the white ring inside and that’s what was off on mine.
Awesome, very easy to follow, video. I followed the video and my non cranking Troy Bilt pressure washer cranked on the first pull and purred like a kitten. 👍👏😃
Thank you soooo much!! I doubted that this would be my issue because I maintain my power equipment the best I can but I guess I still have a lot to learn. I took your advice and removed the carb…cleaned it out but didn’t find anything substantially wrong (no dirt that I could see and no water), reassembled and BAM….IT’S ALIVE!!!
wow, i can't believe it worked for you. I just did the EXACT same thing and my piece of shit will not start. this is the third time ive tried. fuck this mower
Make sure you have a spark, verify timing if the blade hit anything, spray engine starter and see if it hits (in case fuel delivery is clogged). That's the simple stuff...
THANK YOU SO MUCH LAWNMOWER LADY!!! What is that little white tube coming out of the carburator? The one just above the fuel tube? Every time I Push the air box it squirts fuel Thanks again
Sounds like an overflow port. Maybe a problem with the needle and seat? Perhaps something clogging the priming circuit? When you press the bulb, a few drops of fuel should be injected directly into the carburetor venturi.
Nice job on the video and I think. What made it so good? It was the fact that you explained things before you did them, And then fast forward anytime you torqued down attachment points. It's the first time i've seen one of these plastic carburetors disassembled in all of your special attention to detail and cautionary explanations were extremely valuable. Again really nice job!
Thank you so much! I have never taken my carburetor out before but following your video I did that and discovered lots of water in my gas so I emptied out all the gas and put it all back together as you showed and voila, it started up first try. You saved me a lot of money and boosted my self confidence so much!!!
Water contamination is the number 1 culprit I see that plagues all small engines. The ethanol fuel draws in moisture. Every mower I service, I completely drain all fuel from the tank and carb and leave it out in the sun or dry it bone dry with paper towels. Some models require taking things apart to get out any trapped water. Just a few drops of water can act like a check valve and prevent the gas from getting picked up.
ms LLL - i enjoy watching you disassemble & clean plastic carbs so much, that i've ordered a plastic carb so i can kinda follow along. i'm a manual, rather than visual, learner. this purchase will be difficult to justify, as i don't own a lawn mower. take care. - regards, dLL
You da man,,Sorry Woman,,,this is one of the best videos i have seen,so easy to watch and understand how to clean the carby,,,,,you go girly,and thx heaps for the help
@@TheLawnmowerLady yaaaaa,,,cleaned the carby with eas and full of confridence,thx to you the lawnmowerLady..starts 1st pull ,never ran so good,,,,thankyou,,,,,,you de-woman,,cheers take care
Hello, great video. I've been doing small engine repair for about 5 years now, for a little extra cash and therapeutic reasons (some thing about fixing this little engines). 95% of the time I can get them working just fine by cleaning the carb just as you described, but on a rare occasion after fully cleaning the carb it will still not work properly. I've discovered that the ones that won't work have something in common, looking at the carb body from below (10:45), the hole on the right on a good working carb, blows out the hole at the front intake left inner hole looking at it right side up front view(can actually see the routing on the outside of the carb) the itomizer covers seals that hole with an oring. The ones that just refuse to work right, do not have this holes connected, my thought was that it's obstructed but I'm not so sure anymore. It's driven me crazy trying to find out what actually goes bad with these carbs, I've ordered re pop new ones when this happens, taken them apart a lo and behold the holes mentioned are connected. I disected one to see the obstruction but it seemed that it was built that way, so it got me wondering what I'm missing. They are anywhere from $9-$30 online so its not worth spending too much time on the issue, but it bugs me to have 10 of these laying around that just won't work after a thorough cleaning. I've fixed hundreds of lawn mowers, pressure washers, edgers and anything using this Briggs engine with the plastic carb. You got any idea what happens with this plastic carbs when a cleaning won't get them working right?
If I follow you correctly, that is a block off port on carbs that have a choke mechanism. They are really so cheap , easy to replace the entire thing if a good cleaning won't fix it. Thanks for watching. Cheers!
Great Video ! If I may, blow off the carb. / air cleaner backing and cover with compressed air, this removes 80% of the crud. . then use a longer, soft bristle detail brush with your cleaner. The longer bristles work down in the small areas. I live in Indiana, water is definitely a problem, mostly because folk s believe their 2 car garage is made to store old sewing machines, tread mills and endless non labeled boxes, while leaving the car's and mower outside ! Thank you for the video !
Thank you so much. I figured there was water in there but wasn't sure how to get the whole thing apart. Sure enough, a small swimming pool of water. Drained, cleaned up, and viola ... started up on the first pull!
An awesome video! Your walk through is the easiest to follow. I have a briggs & stratton im trying to fix. Got the carb cleaned thanks to this video but when it was brought to me there was a piece laying on the deck. It's a white curved arm with a hole in one end that must connect to the choke to open and close it. Can you please tell me where it goes. Can't find a diagram for this mower online. Thanks
Hot Damn Thank You Ma'am 😁 I really appreciate how you showed the process, from start to finish. Maybe in my younger days, Just Do It videos would been fine, but now, with Pugalustica Dementia, I like slower, well explained videos when it comes to taking anything apart!! Thank You Much Ma'am Subscribed From Iowa 😊
Great video. I do these alot. One thing I do that I didn't see you do was check for water in the gas tank. I just always take the tank off and clean it out. Clean carb, clean tank. Just a thought for you. Thank you
Great vid, enjoyed it. Wasn't sure I'd reassembled mine in the right order but it seems I have. Mower starts fine now but can't stop it hunting.. governor's back and forth constantly and revs up and down at a rate of about once a second. Thought I had the o-rings in the wrong order on the intake pipe but your vid confirms I've got them right. got fresh fuel in the tank, the fuel feed pipe's clear, and the carb body is a new one. Air filter's clean. There's no variable throttle control as such on mine, there's just a spring and a rod on the governor that goes straight to the throttle butterfly, think it's designed just to start and run at one rpm setting (basic rotary mower with no traction drive). I never took the intake pipe off the block though so I didn't change the red o-ring (there was a new one in with the new carb, I'd wondered where that was supposed to go!). Magneto gap seems ok & there's a good spark, but I've not cleaned or gapped the plug yet. Engine's a 300 (doesn't say 300E, just 300). After reading Anders tip below I found a slew of different jets mentioned on Ebay - 596521,596522,596523,596524 - does anyone have a reference as to what size each is & which engines each jet goes best with? And, can you tell what size the jet module you have just by looking at it?
Sorry you are having trouble. If I read your comments right, it seems you have a replacement carburetor, and tried to clean it? If so, I would try to clean the original and put that back on. I know non-OEM carbs can be problematical. Your symptoms sound like the idle circuit may be clogged. Others drill out the main jet. I have done neither. The different fuel jet stacks are designed for different altitudes. You need a smaller jet size for higher altitudes to keep the engine from running too rich. As to which is which, I can't really help there. If you have a set of micro drill bits, you can size the orifice by which drill bit slides in easily. I wish I could be more helpful. I appreciate you watching.
@@TheLawnmowerLady Thanks.. yes replacement carb off Ebay. I've never met an all-plastic carb before. Used to work as a lawnmower service tech here in UK but that was a quarter century ago. I tried cleaning the original carb but wasn't sure how to get the jet out; I figured it was non-removable and a new carb was only £10 or so. So I'm now wondering if the new carb I got, has the wrong size jet in it. Now I know how to safely remove the jet module I'll try removing & cleaning the one in the original carb. Should have googled you up right from the start!
@@nginmumbetse7894 I suspect your replacement carb is a victim of poor tooling. Some tiny passage is not completely bored out or something. Best of luck to you.
@@TheLawnmowerLady Went back to the start & followed your guidance to clean up the old carb. Noticed the jet module in the old carb, once I finally had it out, was blocked in both the copper jets. Cleaned them out & once I could get an idea of their true size, realised the jet pack supplied with the new carb had holes WAY smaller. I put the cleaned, old jet pack into the new carb body, reassembled.. mower now runs great. Although the new carb I ordered was listed for a 300 engine (amongst others), I guess the supplied jet was just too small. I discovered the jet module is in two parts - there's an inner and an outer part to it and they come apart. Sometimes when you pull out the jet module, only the inner comes out and leaves the outer bits stuck down the hole. With the inner and outer parts of the jet module seperated, you can get at the air emulsion holes on the inner bit, and clean them out.
It would be nice to hear it running after you were done fixing it. Other than that you did one heck of a good job of explaining how to clean that carburetor. Keep up the good work and I'll keep watching. Thank you and God bless.
I appreciate that. I thought that video was getting on the long side, and chose to edit that. Many other viewers said the same thing. Most all my newer vids include start ups. Thanks for watching. Cheers!
When the gas keeps flowing after a few minutes after the lawnmower is off . I call this kinda carb just I'm a have to put a inline shut off valve an change oil n run it til it goes out
Excellent video, could you please help me to save time I did buy a new carburetor same that came with the lawnmower which is the Plastic one but does not start. Suggestions?
Go back over your work. Start with the basics: spark, fuel, and air. Make sure fuel flow is happening by removing the drain plug ( requires a 10mm hex key) th-cam.com/video/dj5cvNhEzV0/w-d-xo.html this video shows how that works.
The primer bulb "primes" the engine with a small amount of fuel directly into the venturi of the carburetor. Sort of like a can of starter fluid, without the aerosol can.
Bad gas and water seem to be the problem with a lot of the mowers I run across. I have also found that if you clean the spark plug with a hand powered wire brush then starting fluid and compressed air you almost never need a new spark plug.
Great video, I’m having issues with my mower surging and I think I have to clean it so this video helped me out some on how to take them apart. I am not mechanically inclined in the least but I have to do something about the surging because it’s extremely annoying lol. Anyways thanks for the video and wish me luck that I don’t mess the mower up even more
Thank you for your great video . I have a question I thought to save time I bought a new plastic carburetor exactly the same one you are showing I bought it from Amazon. but after installing it exactly as you are showing. my mower did run for a minute or so and stopped/ I try a couple times same result. What to do. Appreciate any suggestions Murillo
The Briggs 450e benefits from opening the carb jet to 20 thousandths - a stripped bread wire tie can be used to check that the jet is clear and big enough. Doing this helps the motor run better and cuts down on the need for carb cleanings. 👍
This is a good video showing some details about the tier 4 jetting and the prime and start Briggs. My buddy gave me a 2015 ready start version of the 550EX that uses paper element, but can probably be converted to foam by removing one linkage. Thanks!
Just bought a mower just like you showed, used. I have one question, you might can answer. On the gas tank is what looks like an air inlet. I have seen were other tanks for the module don't have. Yet, the carb has an air inlet pc sticking out looking like it is barbed to fit an hose on. Question? Is these pcs suppose to stay open were dirt and dust can get in on the carb and on the tank blow gas in on the air filter or are these inlet suppose to have an hose connection between the two. I have seen in some carb sales were they have an fuel hose and a smaller hose. I don't know? Maybe you can help me out on this. I am running it right now with an little hose connecting between them. I probably don't need it since I seen the video you showed didn't have it. Thanks for any help Enjoyed the video.
I was hoping you would show how that float valve seal was removed. Do you have any videos on replacing the floater valve seal on a plastic carburate and can you tell me about that little plastic valve above the gas line what it's used for and if it's suppose to be attached to another valve like it?
If I understand you correctly, you are talking about the needle valve seat? Where the rubber tip on the needle sits and seals the fuel flow? If so, I have never seen any one remove one, and not sure why unless it was damaged? I don't think it's even available as a separate part. The white plastic fuel barb is a breather overflow
@@TheLawnmowerLady my bad. I figured out why I don't have a seal inside where the floater valve is. It's because the tip of the floater valve has the rubber seal on it. Thanks for the video and the quick response. 👍
@@PardonTheInteruption1 If you suspect the needle is not sealing correctly, you can buy it (needle with the rubber tip) separately, but not the brass seat that is molded into the carburetor body. Thanks for watching.
I squeeze the top lever way up on the top of the lawnmower push handle. It does not engage the throttle. Is there a spring or linkage missing? My customer's mower with this same carburetor (B&S 450e 125cc) I had replaced the needle and needle seat. Took out the atomizer assembly per your video here. Used guitar wire to clean out every hole and orifice then Put it all together. Everything is put back in place. Throttle linkage is properly attached to return spring but engine will not start unless I use starting fluid. Runs 3 seconds and dies.
The handlebar lever engages a brake pad on the flywheel at the same time it disconnects the kill wire. It really is not part of the throttle mechanism. I would be disassembling the carb again to ensure all the seals and o-rings are intact. Clearly there is a fuel delivery issue.
@@TheLawnmowerLady i found the problem! I ordered a float bowl needle. I put it in along with the viton rubber needle seat. (WRONG!) When I opened up the carb, there was not gasoline inside it. So you were right, it was a fuel delivery issue. I took out the rubber needle seat and put everything back together. Runs perfect after priming the carb via the primer bulb. I learned something from you, Thank you. A 66 yr. old dude in the Suburbs of Atlanta, Ga.
Great video. Others go too fast or don't have the camera close enough or even on the subject matter. I have taken my carb apart a few times when the machine either doesn't start or won't stay running. That's where I stand right now. Cleaned carb, new air filter, new plug, new gas...still doesn't stay running then can't get it going again when it stops. Thanks for any hints.
Thanks for watching Ms Annette. Be sure all the small holes are clear in that plastic fuel stack. Ensure the bowl is on correctly. There is a small depression in the bowl that should sit directly below that fuel stack. You might need to turn it 180deg. Other than a collapsed fuel line. Those are the ones I can think of. Oh and check that small donut ring has not rotated out of place. If your carb has a second spring that attaches to the front choke flap, make sure it is not fouling on the metal bracket that the air box is attached to. I hope this helps.
If the mower starts OK after standing for a while but stops running after a couple of minutes, you may have a blocked air vent in the Fuel Cap. This causes a vacuum to occur in the Fuel Tank which prevents the fuel flowing into the carburettor. Prove this by running the mower outside with the Fuel Tank Cap removed -if it keeps running OK then the Fuel Tank Cap venting is the problem. You can take the cap apart to see how it vents and if there is any blockage.

I drill out the bottom main jet with a # 72 drill bit .025 works great , starts first pull ,,,,even the ones without the auto choke . Been working on mowers for over 50 years ,,,I'm a 74 year old machinist and I'm like you " Old School " !
I like to think of it as Old School Cool! I've not modded my lawnmower carbs yet, Thank you Mr. Barry for the tip!
Great video,, what is the white nipple sticking out the side of the carb,, nothing plugs in to it??
@@JoseGomez-yv5vt It's a plug covering up a passage in the carburettor not used on this particular model.
Hey @barryestell6324 is it just the middle bottom inlet that you drill to .025
This person will go to TH-cam heaven for this in-depth video
I hope so! LOL. I appreciate you watching!
I’ve fixed a lot of things with TH-cam videos, and yours is the best. No skipped steps, no dumb product placement, clear AF, and really good editing and production. I’m going to see if you have one on chainsaws after I mow my lawn
Thanks for your kind comments. Cheers!
By far, one of the best videos on how to clean these little plastic carbs. Followed it step by step. Lawnmower fired right up. Thank you.
Happy to help
I appreciate you watching!
Best carb video so far. You are clear and concise. I especially like the fact that you show the whole process without all the chatter and filler.
I'll definitely check your videos first. Great job.
Wow, thank you!
I would like to take a moment to thank you so much for your how to step by step video. It was Christmas Eve 2022 and our lawn mower began losing power and stalling on sloping surfaces ran fine on even ground. I disambled the carbureator and found it full of water also found the breather hose not connected to the air filter. After performing all the steps in this video our lawn mower is back up and running and no longer losing power or stalling when mowing on a gradient/slope. Your video has saved us time, money and a whole of stress as we were about to give up and send mower for repair. Thanks agin so much!!!!!!
Glad to help! Cheers!
Wow! Fantastic video. I tried to repair my Briggs & Stratton pressure washer engine with no help or video. I did most of what she said (it turns out) BUT, I learned three critical things from this vid that I never would have found on my own. Great advice, great quality video, very clear and VERY Helpful. Started the machine on the first pull and it runs like a dream, after sitting dead for two years. Thank you, Lawnmower Lady!
Glad to help. Thanks for watching!
Thank you, Lawnmower Lady! Every year, it's the same thing - my lawnmower won't start, so I pull out the carburetor, clean it out, then it starts right up. This year, I repeated the process, but it wouldn't start. I was scratching my head and after enough wasted time, I pretty much decided I was going to go buy a battery-powered lawnmower after work, that is, until your video popped up in my feed. I saw the problem at 8:00, the white donut ring had popped out of my carburetor when I had removed it from the lawnmower. I had no idea it had gone missing (and didn't even know to look for it as everything looked ok inside there once I popped the fuel stack back in). I went back out to the garage and found it camouflaged with lots of junk on the floor, put it back in, and the lawnmower started right up! Thank you for your detailed instructions, just enough info to get right to it and point out all of the important parts, but not too much like some others can do. I especially appreciate that you showed how to pull the carb off of the lawnmower (I had figured that out on my own previously, but it helps to see the whole process - and...pulling off the cover is super simple and makes removing the carb easier) - other folks just start their videos after they've pulled the carb out. Looks like the ole' gas-powered lawnmower will survive another summer.
Thanks! Your comments are music to my ears. I'm so glad I could help. Some of those have a black donut ring collar,, and those are nearly impossible to find in the dark recesses of the garage. Cheers!
I cleaned my carb with no success, now I'm going to look around my garage for a donut ring LoL
I watched half a dozen of these videos on this carburetor cleaning, and this one was a stand out. She walks you through the relatively easy (once she shows how) method to remove the linkages from the unit (I messed it up the first time I tried doing the clean). Further she did another breakdown of the nylon stack which no other video showed and all I can say after doing this, was able to finally get my lawnmower to run. Don't waste your time on the other videos; start and end with this one. Nicely done "Lawnmower Lady"!
Thank you! I appreciate that. Cheers!
Madam, thank you very much. With the help of this video, I just removed and cleaned the carburetor on my 450E for the first time ever.
Yay! Happy to help. Cheers!
Very nice work! Clear and concise. The only thing I would have done differently is drained the tank and started with fresh fuel, since there was so much water in the carb previously and you were not sure where it came from. I definite learned a couple of things from this video! Liked and subbed!
Thank you Mr. Eric for the sub and the suggestion. I did indeed drain the tank, but I figured the video was getting a little long.
Thankyou.. been working on small engines for 40yrs and I just couldn't figure out this plastic carb.. you made it easy to figure out how to clean it and now it works like new again! You ROCK!
Glad it helped. As much hate as there is out there for these carbs, they really are pretty simple. They are more prone to getting clogged up with debris that gets sucked into the carb throat. I appreciate you watching. Cheers!
Wow! Even my favorite small engine repair channel did not show that you could separate the atomizer out to clean it. Glad I stumbled across your video.
Glad I could help. Thanks for watching. Cheers!
Excellent video. I have a Hyper Tough with one of these plastic carburetors. I did remove, disassemble, and clean the carburetor, but at the time didn't know about snapping the one section out. So, I will do that at the end of the season. I actually like these plastic carburetors and think they are pretty simple compared to others I have cleaned.
Very well explained and filmed video. Thank you.
Glad it helped. A lot of people complain, but I think the simplicity is a bonus.
Thanks a bunch, ma'am! My mower is back up and running, saving me both the diagnostic fee and the labor, which was going to be more than my mower was even worth at this point. You're amazing, and the instructions were clear enough my child could have done this. Really appreciate it!
I'm so happy to help. I appreciate you watching. Cheers!
Just wanted to say Thank You for ur videos! I've never had anyone to help teach me how to do repairs on my equipment before so when I came across ur videos, it was a tremendous help! You have the best details and information, where other videos just rush thru... I was successfully able to do the repair I needed to get little mower going again!
Thanks a bunch! Hope u stay blessed and happy!
Happy to help. I appreciate you watching. Cheers!
This is the best video on cleaning the plastic carb, the only thing I would do is I would drain the tank because of how much water was in the carb. Please keep doing these videos.
Thank you Mr zoomboy for watching! I did indeed drain it, but edited it out as the video was getting a bit long. Cheers!
Thanks!
And a SUPER thanks for watching, and supporting my channel. Cheers!
Replaced the entire filter box & primer assembly & it started up ran for about 30 sec & cut off. Definitely thankful for your disassembly vid of this carb cause I suspect water is trapped in carb preventing fuel from reaching combustion chamber. Great vid. Thanks a bunch.
Glad to help. Thanks for watching. Cheers!
Thank you so much for this video!! First time working on this type of carb. Your delivery on instructions is clear and precise. I was able to repair my son’s lawnmower.
Glad it was helpful!
I just came down here to thank you for making and posting this video. I was researching my carburetor issue on my mower when I found iy. Now that I liked and subscribed, I have only one question left to ask: can you adopt me? You are the coolest grandma ever. I wish, I’d had somebody like you in my life growing up. I bet, I could pick up a lot just watching you loitering around your workbench. Thank you again!
Awww. That's so nice of you. Thanks for watching. Cheers!
I hate to say it, I saw a woman, and thought, oh no here we go. But you completely made me have to rethink my attitude. Your very thorough and clear. ❤️ thank you for a great video.
Thank you Mr. John. You comment makes me smile! I hope you stick around.
Great video as always! Engines with the plastic carb has a tendency to surge due to the small jet. According to Briggs they run very lean due to emission regulations in different states. They surge a lot here in Europe too. A tip here for all if your carb is clean and it still surges - is to upgrade to a bigger jet - Briggs part no 596524. That often fixes the problem. Personally I prefer to old carbs where you could adjust the mixture. :) Cheers!
Great tip Mr. Anders! Thanks again for watching :)
just think abt this for a minute.. briggs uses the same exact carb , with same exact jets, throat size, ect for 4.5. 5. 5. 5 , 5.75 hp mowers... how are they achieving this wide difference in hp, with the same carb? I dont think they are., I think its a scam. most of the new generation has never used a real 5 hp engine so they dont realize the difference.. they jets are way too small to pass enough fuel for the hp they claim., also the throat of the carb is restricted by a plastic ring .. why did they do this? I think its to restrict air. the engine operates under vacuum, and can only pull so much fuel out of the jets under a specific vacuum and volume.
another problem with the plastic carb design is the 90 degree bend in the white jet chamber.
anytime a fluid or vapor has to make a 90 degree turn, it causes resistance by a factor of 5.
example.. if you put a 90 degree fitting in a garden hose, it is equal to 5 extra feet of hose that the water has to travel thru..
its amazing that these mowers run at All.
Interesting & thanks for the part number. Mine's what I call 'hunting' quite badly.. think that's the same thing as 'surging'.. Might give the different jet a go if cleaning the plug doesn't help. EDIT nice one - you set me on the right path to getting it sorted, using the old original jet (totally blocked, but once cleaned, turned out to be way bigger than the jet that came with the replacement carb I ordered off Ebay)
If jets are not available, you can use a .020" pin vise or drill bit, whatever you like to call it & drill the jet out. I have had a 100% success rate so far.
@@jackwarren3882 A video by Steve's Small Engine Saloon also mentions drilling out the jet to prevent it from clogging again. I noticed the "High Speed Steel Micro Drill Bit Set, 30 Piece" for $3 from Harbor Frieght has a bit this size. It's .5mm (same as .020").
But I'm wondering instead if just installing a fuel filter will also prevent it?
Wow. You're a phenomenal instructor. Subscribed!
Thanks and welcome. Cheers!
Thanks for your help, Lawnmower Lady! Your video is THE best for cleaning these plastic carburetors! 👍🏼👍🏼
You are so welcome!
Thank you for your video, It worked first pull after this videos repair! Avoided spending 600 on a new "modern" electric mower
Glad it helped. Cheers!
Thanks for the instructional video. Just picked up a Craftsman mower someone was throwing out. Cleaned the carburetor with your video direction and runs like a champ! Thanks again.
Glad it helped Mr. Jim! hope you subscribe and stick around. Cheers!
This is the most detailed video that I have found on this subject. Now I know where that large black O ring came from that fell out when I pulled the carb off. And i didn't know that the white hard plastic O ring snaps in on top of it. Thanks.
Thanks for watching Mr Gary! I'm happy my video helped you. Cheers!
Me too! Found an o ring had no idea where it fell from. White plastic ring was still inside the carburetor. Thank you so much!
Here is an idea that helped me. I added an inline round disc fuel filter between the tank and carb. The type with the 150 micron metal mesh in it. Doing that has helped prevent the clogged carb jet issue. These are great mower engines.
Good idea.
Thank you.
Köszönöm a precíz bemutatást! Dadogva járás után leállt; gondoltam kipucolom a karburátort, de ilyet még nem szedtem szét . . . Szerencse, hogy rátaláltam - bár majd' az összes szerszámom megvan hozzá - biztosan eltartott volna fél napig amire megcsinálom! Külön köszönet a viszonylag (kis műszaki tudással!) "érthető", MAGYARRA állítható automatikus fordítást ;-) Viszem a szervizbe . . .!
Köszönöm, hogy megnézted a videómat. Remélem, ezzel időt és pénzt takaríthat meg. Egészségére!
Thanks for the detailed directions on the rebuild. I spent all day trying to put this thing back together. I watched your video and you mentioned the white ring inside and that’s what was off on mine.
Glad I could help. Vey easy to miss that. Cheers!
Awesome, very easy to follow, video. I followed the video and my non cranking Troy Bilt pressure washer cranked on the first pull and purred like a kitten. 👍👏😃
Great to hear!
Thank you soooo much!!
I doubted that this would be my issue because I maintain my power equipment the best I can but I guess I still have a lot to learn. I took your advice and removed the carb…cleaned it out but didn’t find anything substantially wrong (no dirt that I could see and no water), reassembled and BAM….IT’S ALIVE!!!
Glad I could help!
wow, i can't believe it worked for you. I just did the EXACT same thing and my piece of shit will not start. this is the third time ive tried. fuck this mower
Make sure you have a spark, verify timing if the blade hit anything, spray engine starter and see if it hits (in case fuel delivery is clogged). That's the simple stuff...
THANK YOU SO MUCH LAWNMOWER LADY!!! What is that little white tube coming out of the carburator? The one just above the fuel tube? Every time I Push the air box it squirts fuel
Thanks again
Sounds like an overflow port. Maybe a problem with the needle and seat? Perhaps something clogging the priming circuit? When you press the bulb, a few drops of fuel should be injected directly into the carburetor venturi.
Best job I’ve seen for this model by far, keep up that Excelent work.
I appreciate you watching!
Nice job on the video and I think. What made it so good? It was the fact that you explained things before you did them, And then fast forward anytime you torqued down attachment points. It's the first time i've seen one of these plastic carburetors disassembled in all of your special attention to detail and cautionary explanations were extremely valuable. Again really nice job!
Awesome! Thank you!
Great video, I'm a 2 stroke mechanic, and of course my own equipment is a mess! First time encountering a plastic carb so needed help with my mower!
Glad to help! Thanks for watching. Cheers!
What a fantastic video!!! Great job taking your time and explaining everything thoroughly and speeding up the non-educational pieces.
Glad it was helpful!
Thank you so much! I have never taken my carburetor out before but following your video I did that and discovered lots of water in my gas so I emptied out all the gas and put it all back together as you showed and voila, it started up first try. You saved me a lot of money and boosted my self confidence so much!!!
Yay! Your comments are music to my ears. So happy to help. Cheers Ms Iana!
Water contamination is the number 1 culprit I see that plagues all small engines. The ethanol fuel draws in moisture. Every mower I service, I completely drain all fuel from the tank and carb and leave it out in the sun or dry it bone dry with paper towels. Some models require taking things apart to get out any trapped water. Just a few drops of water can act like a check valve and prevent the gas from getting picked up.
ms LLL - i enjoy watching you disassemble & clean plastic carbs so much, that i've ordered a plastic carb so i can kinda follow along. i'm a manual, rather than visual, learner. this purchase will be difficult to justify, as i don't own a lawn mower. take care. - regards, dLL
Right on!
You da man,,Sorry Woman,,,this is one of the best videos i have seen,so easy to watch and understand how to clean the carby,,,,,you go girly,and thx heaps for the help
I appreciate that! Cheers!
@@TheLawnmowerLady yaaaaa,,,cleaned the carby with eas and full of confridence,thx to you the lawnmowerLady..starts 1st pull ,never ran so good,,,,thankyou,,,,,,you de-woman,,cheers take care
Hello, great video.
I've been doing small engine repair for about 5 years now, for a little extra cash and therapeutic reasons (some thing about fixing this little engines).
95% of the time I can get them working just fine by cleaning the carb just as you described, but on a rare occasion after fully cleaning the carb it will still not work properly.
I've discovered that the ones that won't work have something in common, looking at the carb body from below (10:45), the hole on the right on a good working carb, blows out the hole at the front intake left inner hole looking at it right side up front view(can actually see the routing on the outside of the carb) the itomizer covers seals that hole with an oring.
The ones that just refuse to work right, do not have this holes connected, my thought was that it's obstructed but I'm not so sure anymore.
It's driven me crazy trying to find out what actually goes bad with these carbs, I've ordered re pop new ones when this happens, taken them apart a lo and behold the holes mentioned are connected.
I disected one to see the obstruction but it seemed that it was built that way, so it got me wondering what I'm missing.
They are anywhere from $9-$30 online so its not worth spending too much time on the issue, but it bugs me to have 10 of these laying around that just won't work after a thorough cleaning.
I've fixed hundreds of lawn mowers, pressure washers, edgers and anything using this Briggs engine with the plastic carb.
You got any idea what happens with this plastic carbs when a cleaning won't get them working right?
If I follow you correctly, that is a block off port on carbs that have a choke mechanism. They are really so cheap , easy to replace the entire thing if a good cleaning won't fix it. Thanks for watching. Cheers!
You just gave me two answers to a problem I had with this carb ! Bless you !!! Henry sent me . 👍
Thanks Bill, glad I could help. Hope you stick around!
I've watch several videos and yours is by far the best. Thanks my lady!
Yay! Thank you!
First time I’ve seen inside the plastic carb. Very simplistic. Thanks
Glad to help. Cheers!
thank you for the breakdown on the plastic carbs lawnmower lady. it was the atomizer dissasembly that solved my riddle. you rock.
Thanks Mr Mike! Glad I could help. Cheers!
Great Video ! If I may, blow off the carb. / air cleaner backing and cover with compressed air, this removes 80% of the crud. . then use a longer, soft bristle detail brush with your cleaner. The longer bristles work down in the small areas. I live in Indiana, water is definitely a problem, mostly because folk s believe their 2 car garage is made to store old sewing machines, tread mills and endless non labeled boxes, while leaving the car's and mower outside ! Thank you for the video !
Thanks Mr. Toon for watching. Hope you subscribe and stick around!
Thank you so much. I figured there was water in there but wasn't sure how to get the whole thing apart. Sure enough, a small swimming pool of water. Drained, cleaned up, and viola ... started up on the first pull!
Glad to help. Thanks for watching. Cheers!
Excellent DIY video. Thanks a million, dear lady.
Thank you! 😊
Awesome video, explained well, precise, and very helpful one of the best vids on youtube big ups to you.
I appreciate you watching. Cheers!
So far you the best one I found on here youre brilliant
I appreciate you watching. Cheers!
An awesome video! Your walk through is the easiest to follow. I have a briggs & stratton im trying to fix. Got the carb cleaned thanks to this video but when it was brought to me there was a piece laying on the deck. It's a white curved arm with a hole in one end that must connect to the choke to open and close it. Can you please tell me where it goes. Can't find a diagram for this mower online.
Thanks
I'm not sure, try Googling: "briggs and stratton plastic carburetor parts diagram" Hope this helps. Thanks for watching.
my dear, best video on carb clean on you tube, sooo concise.
Thank you Mr Greg! I appreciate you watching. Cheers!
Your video helped me so much, thank you! I’ve used a lawn mower but never fixed one until today.
So glad I could help. I appreciate you watching. Cheers!
Hot Damn Thank You Ma'am 😁
I really appreciate how you showed the process, from start to finish.
Maybe in my younger days, Just Do It videos would been fine, but now, with Pugalustica Dementia, I like slower, well explained videos when it comes to taking anything apart!!
Thank You Much Ma'am
Subscribed From Iowa 😊
I appreciate you watching. Cheers!
Thank you. Mower is running and got the yard cut.
Great job!
Great video. I do these alot. One thing I do that I didn't see you do was check for water in the gas tank. I just always take the tank off and clean it out. Clean carb, clean tank. Just a thought for you. Thank you
Thanks for watching.
Thanks for telling the size sockets to use
You bet!
Great vid, enjoyed it. Wasn't sure I'd reassembled mine in the right order but it seems I have. Mower starts fine now but can't stop it hunting.. governor's back and forth constantly and revs up and down at a rate of about once a second. Thought I had the o-rings in the wrong order on the intake pipe but your vid confirms I've got them right. got fresh fuel in the tank, the fuel feed pipe's clear, and the carb body is a new one. Air filter's clean. There's no variable throttle control as such on mine, there's just a spring and a rod on the governor that goes straight to the throttle butterfly, think it's designed just to start and run at one rpm setting (basic rotary mower with no traction drive). I never took the intake pipe off the block though so I didn't change the red o-ring (there was a new one in with the new carb, I'd wondered where that was supposed to go!). Magneto gap seems ok & there's a good spark, but I've not cleaned or gapped the plug yet. Engine's a 300 (doesn't say 300E, just 300). After reading Anders tip below I found a slew of different jets mentioned on Ebay - 596521,596522,596523,596524 - does anyone have a reference as to what size each is & which engines each jet goes best with? And, can you tell what size the jet module you have just by looking at it?
Sorry you are having trouble. If I read your comments right, it seems you have a replacement carburetor, and tried to clean it? If so, I would try to clean the original and put that back on. I know non-OEM carbs can be problematical. Your symptoms sound like the idle circuit may be clogged. Others drill out the main jet. I have done neither. The different fuel jet stacks are designed for different altitudes. You need a smaller jet size for higher altitudes to keep the engine from running too rich. As to which is which, I can't really help there. If you have a set of micro drill bits, you can size the orifice by which drill bit slides in easily. I wish I could be more helpful. I appreciate you watching.
@@TheLawnmowerLady Thanks.. yes replacement carb off Ebay. I've never met an all-plastic carb before. Used to work as a lawnmower service tech here in UK but that was a quarter century ago. I tried cleaning the original carb but wasn't sure how to get the jet out; I figured it was non-removable and a new carb was only £10 or so. So I'm now wondering if the new carb I got, has the wrong size jet in it. Now I know how to safely remove the jet module I'll try removing & cleaning the one in the original carb. Should have googled you up right from the start!
@@nginmumbetse7894 I suspect your replacement carb is a victim of poor tooling. Some tiny passage is not completely bored out or something. Best of luck to you.
@@TheLawnmowerLady Went back to the start & followed your guidance to clean up the old carb. Noticed the jet module in the old carb, once I finally had it out, was blocked in both the copper jets. Cleaned them out & once I could get an idea of their true size, realised the jet pack supplied with the new carb had holes WAY smaller. I put the cleaned, old jet pack into the new carb body, reassembled.. mower now runs great. Although the new carb I ordered was listed for a 300 engine (amongst others), I guess the supplied jet was just too small. I discovered the jet module is in two parts - there's an inner and an outer part to it and they come apart. Sometimes when you pull out the jet module, only the inner comes out and leaves the outer bits stuck down the hole. With the inner and outer parts of the jet module seperated, you can get at the air emulsion holes on the inner bit, and clean them out.
@@nginmumbetse7894 glad you got it running. Cheers!
This video was very helpful and helped me get my two lawnmowers back started
Happy to help.
Thank you so much for your excellent tutorial ,all sorted running like a good one,all the best from the U.K.
You're welcome!
Great video, I didn't know the plastic carburetor could be serviced. Thanks
Glad to help. Cheers!
Wow - you were born to teach, thank you so much
My pleasure!
Thank you this was the best video for this repair I have seen 👍👍👍
Wow, thanks!
Just discovered your videos here in UK. Found to be very informative simple and clear and concise. Thank you
Glad you like them Mr Richard! Cheers!
Great video, thanks. Would suggest you start engine at the end as final fix proof.
Thanks for watching. Some videos go too long, and I have to make cuts.
It would be nice to hear it running after you were done fixing it. Other than that you did one heck of a good job of explaining how to clean that carburetor. Keep up the good work and I'll keep watching. Thank you and God bless.
I appreciate that. I thought that video was getting on the long side, and chose to edit that. Many other viewers said the same thing. Most all my newer vids include start ups. Thanks for watching. Cheers!
Great video. Now you've helped getting a lawn mowed in Ireland!
Happy to help. Cheers! Or I guess I should say Sláinte!
Love those plastic carbs! Easy to remove and clean.
Yes they are. Thanks for watching!
Takes longer to remove and clean tank than to kit carb love them
When the gas keeps flowing after a few minutes after the lawnmower is off . I call this kinda carb just I'm a have to put a inline shut off valve an change oil n run it til it goes out
What does numbers on gas cap mean. Usually in lawn mower I just add gas and I suppose to only use a certain kind never noticed before
Usually recommends the maximum amount of ethanol. Zero ethanol is best.
You did great!! Thank you for making this video for all of us to see you do this task.
You are so welcome!
Thanks to you, I JUST FIXED MY MOWER. THANK YOU
Yay! I appreciate you watching. Cheers!
Excellent job showing every step necessary.

Happy to help!
I’m so glad I stumbled across this. It was extremely helpful !
Glad it was helpful! Thanks for watching.
Excellent video, could you please help me to save time I did buy a new carburetor same that came with the lawnmower which is the Plastic one but does not start. Suggestions?
Go back over your work. Start with the basics: spark, fuel, and air. Make sure fuel flow is happening by removing the drain plug ( requires a 10mm hex key) th-cam.com/video/dj5cvNhEzV0/w-d-xo.html this video shows how that works.
Great video! Thank you for explaining everything the way you do. You're a great teacher!
Glad it was helpful! Cheers!
What's the purpose of that primer bulb on these engines?
Your video helped me tremendously, I remove the carburetor cleaned it put it back on now runs
The primer bulb "primes" the engine with a small amount of fuel directly into the venturi of the carburetor. Sort of like a can of starter fluid, without the aerosol can.
I am working on right a carb and this was very helpful to me. Thanks
Glad it helped
Bad gas and water seem to be the problem with a lot of the mowers I run across. I have also found that if you clean the spark plug with a hand powered wire brush then starting fluid and compressed air you almost never need a new spark plug.
I'd say bad gas is +90% of all my repairs.
Excellent video, you went step by step on each rubber gasket. Thank you very much. 🥰🥰🥰
I appreciate you watching. Cheers!
Perfect ! My engine start again ! Thanks again !
Happy to help!
Great video, I’m having issues with my mower surging and I think I have to clean it so this video helped me out some on how to take them apart. I am not mechanically inclined in the least but I have to do something about the surging because it’s extremely annoying lol. Anyways thanks for the video and wish me luck that I don’t mess the mower up even more
Take your time, and take pictures to help you reassemble. You’ll be fine. Check that air filter is clean too. Thanks for watching.
@@myvicariouslife4012 Glad you got it fixed. Hopefully next time it won't be so blazing hot. Cheers!
thank you so much, exactly what I needed ! Cheers from France!
Great to hear. Cheers! or I guess I should say Votre santé!
Super helpful, thank you! Engine now working beautifully!
Glad it helped!
Hello, nice video, I have the same carb. What is the wight nipple above the fuel inlet for? Nothing is hooked up. Thank you.
I think on other models, it might be a overflow, but it's just a plug. Thanks for watching.
Thank you for your great video . I have a question I thought to save time I bought a new plastic carburetor exactly the same one you are showing I bought it from Amazon. but after installing it exactly as you are showing. my mower did run for a minute or so and stopped/ I try a couple times same result. What to do. Appreciate any suggestions

Sorry I missed this, check out the other message.
LOL…going through your back catalog. This thing with all the different men’s shirts is a real hoot!
I really appreciate you watching my channel!
Thanks, it's fix now
Cutting gas tomorrow 😊😊😊
Thank you so much for your help! Just about have the carburetor out; will finish the rest in the a.m.
Fantastic!
@@TheLawnmowerLady It is fantastic 4sure...thanks to you!
The Briggs 450e benefits from opening the carb jet to 20 thousandths - a stripped bread wire tie can be used to check that the jet is clear and big enough. Doing this helps the motor run better and cuts down on the need for carb cleanings. 👍
I know a lot of people do drill them out.
This is a good video showing some details about the tier 4 jetting and the prime and start Briggs. My buddy gave me a 2015 ready start version of the 550EX that uses paper element, but can probably be converted to foam by removing one linkage. Thanks!
I appreciate you watching. cheers!
Just bought a mower just like you showed, used. I have one question, you might can answer. On the gas tank is what looks like an air inlet. I have seen were other tanks for the module don't have. Yet, the carb has an air inlet pc sticking out looking like it is barbed to fit an hose on. Question? Is these pcs suppose to stay open were dirt and dust can get in on the carb and on the tank blow gas in on the air filter or are these inlet suppose to have an hose connection between the two. I have seen in some carb sales were they have an fuel hose and a smaller hose. I don't know? Maybe you can help me out on this. I am running it right now with an little hose connecting between them. I probably don't need it since I seen the video you showed didn't have it. Thanks for any help Enjoyed the video.
Sometimes those are overflow ports, some are just plugs for unused ports. Thanks for watching. Cheers!
I was hoping you would show how that float valve seal was removed. Do you have any videos on replacing the floater valve seal on a plastic carburate and can you tell me about that little plastic valve above the gas line what it's used for and if it's suppose to be attached to another valve like it?
If I understand you correctly, you are talking about the needle valve seat? Where the rubber tip on the needle sits and seals the fuel flow? If so, I have never seen any one remove one, and not sure why unless it was damaged? I don't think it's even available as a separate part. The white plastic fuel barb is a breather overflow
@@TheLawnmowerLady my bad. I figured out why I don't have a seal inside where the floater valve is. It's because the tip of the floater valve has the rubber seal on it. Thanks for the video and the quick response. 👍
@@PardonTheInteruption1 If you suspect the needle is not sealing correctly, you can buy it (needle with the rubber tip) separately, but not the brass seat that is molded into the carburetor body. Thanks for watching.
I squeeze the top lever way up on the top of the lawnmower push handle. It does not engage the throttle. Is there a spring or linkage missing? My customer's mower with this same carburetor (B&S 450e 125cc) I had replaced the needle and needle seat. Took out the atomizer assembly per your video here. Used guitar wire to clean out every hole and orifice then Put it all together. Everything is put back in place. Throttle linkage is properly attached to return spring but engine will not start unless I use starting fluid. Runs 3 seconds and dies.
The handlebar lever engages a brake pad on the flywheel at the same time it disconnects the kill wire. It really is not part of the throttle mechanism. I would be disassembling the carb again to ensure all the seals and o-rings are intact. Clearly there is a fuel delivery issue.
@@TheLawnmowerLady i found the problem! I ordered a float bowl needle. I put it in along with the viton rubber needle seat. (WRONG!) When I opened up the carb, there was not gasoline inside it. So you were right, it was a fuel delivery issue. I took out the rubber needle seat and put everything back together. Runs perfect after priming the carb via the primer bulb. I learned something from you, Thank you.

@@bassinbillRC5300 Happy to help. Cheers!
Great video. Others go too fast or don't have the camera close enough or even on the subject matter. I have taken my carb apart a few times when the machine either doesn't start or won't stay running. That's where I stand right now. Cleaned carb, new air filter, new plug, new gas...still doesn't stay running then can't get it going again when it stops.
Thanks for any hints.
Thanks for watching Ms Annette. Be sure all the small holes are clear in that plastic fuel stack. Ensure the bowl is on correctly. There is a small depression in the bowl that should sit directly below that fuel stack. You might need to turn it 180deg. Other than a collapsed fuel line. Those are the ones I can think of. Oh and check that small donut ring has not rotated out of place. If your carb has a second spring that attaches to the front choke flap, make sure it is not fouling on the metal bracket that the air box is attached to. I hope this helps.
If the mower starts OK after standing for a while but stops running after a couple of minutes, you may have a blocked air vent in the Fuel Cap.
This causes a vacuum to occur in the Fuel Tank which prevents the fuel flowing into the carburettor.
Prove this by running the mower outside with the Fuel Tank Cap removed -if it keeps running OK then the Fuel Tank Cap venting is the problem.
You can take the cap apart to see how it vents and if there is any blockage.
