thanks alot steve you saved me alot of money mower works good as new easy fix thanks again michael from baltimore
In a pinch without micro drill bits, I used my torch tip cleaning files.
So gonna try that man thanks so much
I'm a "mature woman" lol & I followed your instructions completely. Worked like magic!!! Much thanks from Georgia!
the link for the micro drill bits is no longer valid, the description of the item is correct, but its not available for purchase, nor are the pictures correct.
I'm a single mom homeowner and I find this guy hilarious! No way I'm paying to have my mower fixed before I try myself. Great video.
That is awesome!
Oh Liz, I totally agree with you. I love this guys videos! And believe me, He knows what he's talking about.
Ahh, a kindred spirit. 👍
I do hope you enjoy a fine amber beverage also!
All well and good just keep in mind most places charge extra if the owner has already attempted to fix it because we then have to fix your problem plus the original problem. None the less have a go at it. It ain't the space shuttle after all lol
Much respect. I own a small engine repair shop in South Carolina. What we do is starting to be a dying trade. Lot of machines are throw aways now a days. The only way I make money is by fixing stuff and not replacing parts. And the worst thing is a customer bringing something back. You take pride in what you do. That itself is a dying art. Donyboy, Taryl and yourself are awesome. I appreciate the time you put into your videos.
Thank You... Were you ever in the 9th Infantry?
No sir.
I’ve seen a ton of these Briggs coming through the shop. I tried drilling out the jet with an old micro drill bit set. Apparently I drilled it too big and it ran too rich. But, I agree, the jets in these things are way too small. Experience is a bunch of compounded mistakes.
Parts are getting out of site. I fix stuff on the side. You can’t charge by the hour you wont have a business long that way. Part time or hoppy or just having something to do can put a few bucks in your pocket. Am older and enjoy working on small stuff. Most dealers wont even touch a weed wacker cause they charge almost the price of a new one.
@@arthurrodesiler3109 And it will take them a week snd a half to fix it, snd you usually have to go by and check the progress. You then get the ole, "I was gonna call you..."
Watched about a half dozen other b&s carb cleaning how to videos and was having no success until I stumbled across yours. Great walkthrough (particularly for the jet and cartridge) and nice close camera shots. Got it started on first pull. Thanks for the great video!
You're Welcome...
John Sladewski same exact thing here...
@@StevesSmallEngineSaloon Thanks, got mine started 1st pull after sitting in the garage for the last year or so. Home Depot wouldn't take their Yard Machine back. Carb cleaner was the answer.
Well try the rest and then listen to the Best. Steve small engine saloon
At 3:39 note that the needle is mounted in a channel on the float. Very important when reassembling the unit. Some folks may just drop the needle in the cavity, causing the float to disengage.
What makes Steve so good as a small mechanic Professional is his ability to test, Diagnose, Re test and check it again. He learns each time he makes a repair. And then what makes steve so great is he's generous with his knowledge and he teaches others. Absolutely fabulous job steve!!!👍👍👍 And have a beer for me.
WOW! Thank You...
72 yr young man here and have flipped a lot of snow throwers, lawnmowers, garden rototillers over the past 40 yrs. Always nice to see someone like Steve who enjoys his work and explain things in detail. I’ll drink to that Steve. 🍺
Right on

I’m a 2367 year old vampire who just awoke from a 300 year slumber. Carburetors weren’t even invented last I was awake. I’m so thankful you put this easy to understand tutorial together for us. This is going to make maintaining the grounds at my castle much easier.
That man is a 'ginormous' talent. Respect due!
Thank You...
@@StevesSmallEngineSaloon hey Steve I need you help I bought a new carbureoter for my mower cause I cleaned it and that didn't fix it so I bought a new one and it still won't run it is not getting fuel to the motor I don't know why ?🤔
I must have cleaned the carburetor three or four times before finding this video. Drilling out the hole on the cartridge to a 20 thousandths of an inch finally fixed it. Thanks much!
Glad it helped
I have a machine that does up-rev motions, why does it do this? It's the carbulator?
Me too! I bought a new one. Used it a few times and now it’s giving issues.
Did drilling it out fix it permanently?
Absolutely great tutorial,.
Thank You...
I just fixed my mower ALL BY MYSELF!! Just now! I'm still greasy.
That thing cranking was the sweetest sound I ever heard!
I can't thank you enough. I just love your channel and WILL BE sharing!
Also, My brother's name is Steve. So I see your merch in his future!
That's AWESOME! Great job Andria....
Good vid,
There are 2 different main jet models ( that cartridge part has normal one and high altitude one).
Parts #592684 (high altitude)
#592792 (standard)
I don’t know what is different about them but perhaps the main jet is a different size
[Original main jet opening may be too small from the manufacturer & may need to be increased in ID with a tiny screw bit to allow better fuel flow after cleaning everything with carb cleaner & blowing dry with compressed air.]
Hi Steve, I just found you for the first time today, have watched four of your videos, & am loving the way you explain things for those of us who have little to no experience with small engines... THANK YOU! I just get worried that there are sometimes not enough closeups of how things look before taking them apart to help me get them back together properly & get all the screws & parts back in the right places & positions! Hopefully, the more vids I watch, the less foreign everything will appear when I get started.
Also, thank you SO MUCH for not having any background music in your videos... concentrating on the details requires all my attention & vids that add music are torture for people with attentional struggles. God bless!

Great video I will be trying all these steps. My pressure washer is only a year old and I ran the gas out last fall and all that jazz but it wont start. My question is are there any metal replacement carbs in this model? why would any one want to deal with the plastic garbage every year? if so, what model carb do I buy? thank you for all the help!
Silly emissions standards, there trying to keep these things running as lean as they can.
My thoughts exactly....
@@StevesSmallEngineSaloon Yeah. My mower has a sticker on it attesting to its "3 out of 10" clean air rating (lower is better); so clearly -- emissions considerations went into the design... which is fine I guess. I just don't want to take it apart more than once per year.
I got four seasons out of my Bolens 140cc B&S. During the first season I was amazed at the gas mileage I was getting. Just the other day I had to go thru the carb twice to get in running again. First time I did not poke the holes. Came up with the bread twist tie the second time. Started on first pull. If it happens again I will drill that sucker out. Enjoyed the video.
Gretta Thunberg will be on Steve's case.
Same crap they do with the 49cc scooter engines, they come jetted way too lean and the carbs are sealed, you have to drill out the screws to open them or just buy an aftermarket carb that is NOT sealed, in order to change jet sizes. They run too lean and people have serious problems up to and including melting a hole in the piston due to that. Screw this plastic carb crap, why not figure out a retrofit with a metal carb? has to be one that would fit, that plastic crap isnt going to last very many cleanings having to PRY the bowl and cartridge with a screw driver to get them out
Couple of points. When removing white cartridge, be very careful if you use small flat blade screwdriver that you insert it deep enough between side of white cartridge and black sidewall so you do not damage the thin O ring at the top of the white cartridge. When reinstalling this cartridge, be aware there is a plastic sleeve that sits in the body of the carburetor between the butterfly valves. It has a hole in the side wall of the sleeve. You cannot see this hole unless you remove the sleeve. This hole in the sleeve lines up with a hole in the body of the carburetor. The central jet of the white cartridge must pass through both of these holes to seat properly. Sleeve can shift while you are working on carb making it impossible to reinstall white cartridge. Cartridge should install with little pressure to seat it properly. If you find it very difficult to reinstall, sleeve probably moved and holes not aligned. To fix this, need to gently remove the larger butterfly valve (throttle) metal piece. It fits into a slot in the small plastic pin the holds it in place. GENTLY spread the slot apart and GENTLY remove this metal piece. You can then pull the pin out giving you access the the White/Grey sleeve. Can use your small finger to reach into space to sleeve. Use small probe and insert it through the hole where the main central jet on the plastic cartridge seats in the carburetor while using your small finger on the sleeve to align the holes. Once aligned, remove your probe but keep your small finger on the sleeve so the holes stay aligned and reinsert the plastic cartridge. Should easily seat in place. Reinstall throttle pin and gently insert the metal piece into the slot in the throttle pin, making sure you have it oriented properly. What should have been a 20 to 30 minute job today took almost 2 hours because of these issues (torn O ring) and trying to figure it out ( as well as breaking that plastic throttle pin and having to glue and clamp it and waiting for it to cure before being able to reinstall it)
I think he heard you. He did another video just to mention this plastic sleeve! Well done!
Do you have a video on this procedure please..
Yikes, I need to read this comment again in future before I attempt any maintenance on this carburetor though, reading this has scared me so much I may never try it now! I would very much appreciate a video that allows me to visualize what you have described here. :)
[9.19.2022]
Many thanks for your important complementary comment.
Great video once again! Yes thats right! do your own work! I started doing my own work 14yrs ago and saved myself a TON OF MONEY, TIME, FUSTRATIONS, WEAR AND TEAR on my car./ and that means I have more time to Drink Beer at the end of the day, Thank you STEVE
It`s a nice tutorial! We have the identical issue with such plactic carb. I have cleaned it thoroughly, however, no difference in outcome. Too difficult to start the engine and... it`s possible one time only. If stop it and try to pull again- no response... The spark is normal, compression is acceptable, but no start. I`ll try to purchase this micro drill set, but, I have a doubt that this is only a problem. Do you know whether I can replace this plastic "masterpiece" with a traditional metal analog, please? How to find a compatible carburetor? Thank you
THANK YOU! just got it running like new! I didn't port the jet, because it already costs $50 to fill the tank and I need the gas mileage 😄
Thank you so much. After watching your videos, my husband and I had our old mower running like new in just a few minutes. We almost threw it away. Thanks again. We are older and on a fixed income, every little bit helps!
You're Welcome...
Hey Steve,
My son brought home a mower that wouldn’t start, I noticed that it had one of those Walbro plastic carburetors. The jet was clogged with what looked like corrosion so I drilled it out with a.04mm drill bit. Blew out the ports with carb cleaner. This mower runs like new.
Thanks so much for your advice and tips. I watch your shoe often.
You're Welcome...
Thanks so much Steve,
My neighbor asked me last week if I knew anything about Briggs & Stratton engines. I told him I've had pretty good luck keeping the two Quantum Briggs motors going on the two mowers I have. My mowers are 20, and 25 years old, and they both came stock with the old 3.75 horse B&S engines. The older of the two was lent to another neighbor who was kind enough to bring it back, not only with a bent blade, but a bent crankshaft and of course the lower seal destroyed, rendering it unable to hold oil. :(
Another neighbor of mine was a scrapper, so I asked him if he had any old Briggs motors around that might have a crank shaft for me. He said he had one, but it was a 6HP quantum that didn't run. I asked what he wanted for it, and he said since it was scrap, just my old motor if I could get this one running.
The 6HP quantum had practically no compression, so I went to pull the head off, only to find that all 6 bolts were loose as a goose. I bought a new gasket, put it back together and it's been running solid for 10 years.
The second, the 20 year old mower I bought new to keep at a second property. It had the same 3.75HP motor as my original, but came with a plastic carburetor, which was tank mounted, and looked like my moriginal, however, it never ran right from day one. It was subject to constant stalling, even when my grass was never an inch overdue for cutting. My scrapper neighbor had another Quantum 6HP laying on the ground beneath the bed of his truck, so I asked him what he wanted. Again, he said it didn't run, so he was fine with an exchange.
That motor had a clogged jet, which is such an easy fix, since the jet is in the bowl retaining nut. That motor has been running solid for 5 years now.
I told my neighbor, if it's a Quantum on his mower that I could probably fix it, so he brought it over yesterday.
It wasn't a quantum. It was a brand new Craftsman that had a new style 6.75HP motor with the same plastic carburetor who went through in your video. He bought the mower new at the beginning of the season and was only able to use it to cut his lawn 3 times before it quit running. It would start right up with a shot of carb cleaner, then quit. I was hoping it was just a stuck float, however the bowl was full with clean fuel when I opened it up.
The main jet was visible, and I couldn't see debris in it, so I figured it was time to search TH-cam...
I couldn't see how the jet assembly was retained in the carburetor until I stumbled on to your video. Thanks. :)
I popped it out, and it still looked clean, however, I couldn't see light through it while shining a bright light against the nylon on the revers side, nor could I blow air through it. I worked a sewing needle around in the hole for a bit, then I could see light shined against the nylon through the hole. I was able to blow air through, then get a shot of carb cleaner to pass through from the other brass inlet with the output port blocked.
I put his mower back together, and of course it started on the first pull and sounded like a brand new mower. Hmm... maybe it runs like a brand new mower because IT IS A BRAND NEW MOWER!!!
I don't get it Steve. Why are plastic carburetors such a problem?
I have a reasonable understanding of metallurgy, and I could see if it were an issue of dissimilar metals, I.E. if the jet were alluminum, pressed into a steel body. But that is not the case. Why should the jets on these plastic carburetors be so easily blocked?
Thanks again for the great video. Like I said, I couldn't tell for certain how the jet assembly was held in the bottom of the carburetor until you showed me.
Steve
P.S. Are you really the man of Stihl? :)
Steve I love the Coors in the picture. I don't suppose you're from Oklahoma are you sir? That seems like something we would do.
I'd cleaned a few carbs, but, this last one was my first "plastic " one. Did not know how to start till I watched this. THANK YOU
Right on John!
Competent and consice.
The man knows his craft.
Thank You...
Hey stevens, this one really helped me. I've had that damn carb off 3 times, cleaning it. Put it back on, it would run for 10,15 minutes, then stop. I was loosing it! Then I watched you man.. drilled that little shit out to 20 thou, wa,la, runs like the wind. Your awesome my man! I thank you, your saving the little guy a few bucks. I appreciate your help and your time. Thank you, God bless..
You're Welcome...
The fuel line should have an in-line filter because its inevitable that debris will get in the fuel, I seem to remember putting one in last time I had to clean the stupid carb out.
Sounds like Micheal has some slightly dirty fuel, defiantly a design flaw in these new carbs. Stevens is the MAN. this make me wanna start doing small engine repair. must be tone of these new carbs out there.
Thanks for the great video, I'm going to try the .020" drill bit trick. Just a note, GumOut Carburetor cleaner will dissolve some manufactures O-Rings on the White metering insert and also some of the plastic of the carburetor bodies. So make sure you pull the O-rings off whatever part you're cleaning. Do it quickly and immediately dry the parts with some canned or compressed air. Oddly at the end of the season it's best to disassemble the Carburetor and and dry all the gas out of it with air before you reassemble it and put it up for the winter. Oh and keep a spare carburetor on hand as they are junk, but inexpensive and will work for a season or two, but hopefully your trick will solve this problem for good on these Carburetors. Super video bud! Best Wishes & Blessings. Keith Noneya
These plastic carbs do suck but your tips are great. I do mobile mower repairs and I stock up on these plastic carburetors just because time is money and it’s easier and faster to replace them when I’m in someone’s driveway. I think I will go through the ones I have in stock and open up the jets on them. Oh and I use old guitar strings to clean jets. 👍🏻
You've got to learn how to play the guitar. Then after you wear out the strings, you will have a set of wire cleaning tools ranging from .013 to .056 (for medium string set (6)).
Tjats exactly what I use for cleaning carburetor jets! Awesome
13s, are you The Incredible Hulk!?!?!
I do the same thing with my 10’s! I use the ball ends as handles. 👍
That's a damn good idea thanks

I had the same issue with my customer.I finally had a carb I put on from a blown engine. I still have that carb I can fix now. Steve,your the best. Many Thanks
Thank You...and You're Welcome...
I promised my elderly neighbor I'd fix his mower and it just happens to be one of these goofy plastic carb models. Once again Steve comes to the rescue. I had never seen a plastic B&S carb before this, and can't believe some company thought this was a good idea. Sorry Steve, I'm from the South and I only drink Iced tea during wrenching!
Thank so much for an Amazingly thorough and detailed video. You've given me the knowledge to now go ahead and try to fix the problem I'm having with my lawnmower carburetor. Thanks!
You are welcome!
Hey! Just subscribed after watching 100+ vids of this carburetors issues and yours is the best! Thanks.
Awesome, thank you!
Briggs & Stratton owe it to their customers to at least suggest this fix.
I think the fuel itself is clogging the jet if it sits for more than a couple of weeks.
Steve thanks so much for an awesome video. I’m by no means a small engine repair guy but followed all your instructions to clean the Briggs & Stratton 725 Exi carburetor on a pressure washer. It literally startled me when it started on the first pull. Unreal and fulfilling experience. Thank you sir!!!
Great to hear!
Your video was very helpful. I got both lawnmowers started. 👍🏽
Great to hear!
The e10 fuel will actually clog the tiny jet.water will also corode the jet
Excellent video, I fix my Lawn mower in minutes. After your tutorial all look easy.
Thanks
Glad to help
I just cleaned one of these Friday and was thrilled to get it running, now I need to get it back and drill the jet out so it will continue running. Love these videos, really helpful for do it yourselfers! Thanks!
You're Welcome...
I installed a shutoff in the fuel line and turn it off and run the engine until it runs out of gas when I'm done mowing. It actually runs for four or five minutes on what's in the bowl. Between that and using stabilized non-ethanol fuel I don't expect problems in the future, but if I do, I now know how to fix it. Thanks, Steve, very clear tutorial!
These carbs are a pain. Fortunately if you screw one up while trying to fix it they are available new for under $20. The ethanol we have to have in the gas here wreaks havoc on them. One more thing - safety glasses when spraying carb cleaner! That stuff at best stings and is not good for your eyes. It doesn't task good in your beer either...And gloves too. My guess is that the jets are so small to meet emissions/use less fuel.
Good catch..trs80
Hi Steve I just ordered a set of drill bits after watching your video through your link. You gave out some great information.
Great to hear!
Lot of great info here. However I do have a problem I put the carburetor together and it starts up but now it leaks. It starts dripping from the bottom of the bowl.
float that snaps into place with the pin in the plastic tabs. May not be snapped in fully or has popped out or slid out not allowing the float to shut fuel off.
Thank you, thank you. Out of the box this mower would not start. Had guys look at it and couldn't figure it out. Stumbled onto your very easy to follow tutorial and even hunted down the drill bits locally. After doing the repair myself, this 65 year-old grandma started the mower on the first pull. Been starting ever sense!
That is AWESOME Audrey! So happy to hear....
Hey Steve, thanks again for another great video! I'm working on one of these for a guy and I'll try your fix. Also, I have in the past used torch tip cleaning needles to clean out the jets in carburetors. Seem to work pretty well if you just need to rod the jet out.
Just found this video after replacing/cleaning my B&S model 09P602-0023-F1 carburetor (on a Troy-Bilt Lawn Edger TB554) for the third time, and paying someone else to fix it previously. I've had this thing since (I think) 2012 - thought I bought a piece of quality equipment, but it has been non-functional for most of that time. I just purchased the micro drill set and if/when this new carb clogs, I'll have a drilled version ready to go in. Really appreciate the insight here - keep up the great work my friend!
Thanks for another great video Steve, I honestly wouldn't have been able to diagnose and fix my equipment without you and many other youtubers sharing yalls experience. You are awesome brother cheers! 🍻
You're Welcome...
Thank you for posting this video, I consider myself semi expert in carburetor removal and cleaning now but more than that thanks for saving me about 125 dollars to have my lawnmover "repaired." Best video i've seen on the subject now for some cold ones! LOL
Right on Isaac...
Great video, Bad choice in Beer's . this job needs a Shiner Bock. Something with Flavor! By the way if you know a guitarist, Get his old guitar strings they are great for cleaning carburetors. Every size you need for small engines.
I own a guitar repair shop and old strings are great for getting in places most things won't!
Mmmm....Shiner Bock, are you a Texas boy?
Thank you, Steve. That's the exact carburetor, and problem I ran into today! Many thanks for showing us how to do that!
Glad to help
Uu
EUREKA!
You discovered Brigg's and Stratton's small engine carborator problem.
They've been wrestling with this for decades...😮
Great job there steve,just came in after getting the mower,450 and this same carby going again.Had the exact same thing happen and had some fuel coming out the jet but it wouldn't run after primer fuel had run out,tried 3 times taking carb off then saw this and run a wire (wire brush wire) through main jet and now running like new,thanks buddy having a Little Creatures beer on you in North Queensland.
I failed to add stabilizer to my fuel over the winter. Sure enough the carb got gummed up. Tried soaking the carb in carb cleaner, nothing. Followed the jet cleaning steps as demonstrated on the video and it started on the second pull. Excellent guide on the Briggs carb.
Thank You...
I sold a mower with that type of engine a little while back and not long after ,the customer came in shop with the engine not running right or even starting, . It was fine dirt clogging the jets, although the tank appeared relatively clean, I cleaned fuel system, strained the fuel, starts and run fine, out it went. This unit came back to the shop for same reason 3 times in the span of a season . I'm scratching my head.....Finally discovered that the little strainer inside the tank was missing, allowing fine particles of dirt to enter carb. After replacing the tank, and mower has been running fine since.
Thanks for the tip on checking that too small little screen in the tank. I'll have to put that on my checklist. You can ASSUME it's there, but .....
Steve, thankx... this is truly the information only available from the seasoned journeyman mechanic’s personal experience with these machines. Your willingness to share this is invaluable to the novice tinkers like me. Buy yourself a beer and send me the bill.
Great to hear!
Great vido, I told my wife the old metal carb works great, so some engineers had to change it, and now the hole is so small it plugs very easily, on our mower the very first tank plugged with less than 1/2 tank ran, and I filled it direct from gas station pump,so no contamination from home fuel jug, and about 1 season I am back inside the carb again plugged and not running, will definitely be getting that small bit set, and drillling it out, I have had old Briggs motors run for years problem free, like 13 years and never draining tank, used only ethanol fuel in it , but it was 18 or 20 hp i don’t remember on a rider mower, if I remember right it says industrial grade or something to that effect, and I don’t baby it when I used on the big lawn, took3 hours running steady to mow, so obviously bigger jet hole in it vs 146 cc little mower for little yard
Steve, I have a 7.25 B&S with the plastic carb that surges. I installed a new carb. It still surges. Do you think if I open the main jet it would fix the surge issue? It does smooth out if I remove the filter and block off the air intake in essence richening up the fuel mixture.
I’m thinking that the reason the jet is so small is due to emissions. The OEM’s are trying to run these engines as lean as they can get away with. That’s why we see so many surging problems in these newer engines. And with no adjustments available, opening up jets is the only weapon you have available. BTW, I hate these newer OHV Briggs push mower engines. Not just because of these carbs, but because of the total lack of repair info available. Seems like Briggs doesn’t want them repaired. I still have not found valve clearance specs for them anywhere.
I totally agree....
.004" -.008" . First manual page 10. m.briggsandstratton.com/qr/1706265146825/
John Acuff the operator's manual I have for the Model 100000 675exi / 725exi series have valve clearance specs @ intake 0.004- 0.008 (0.10-0.20 mm) the same for exhaust..
Thanks for the tip. I think a lot of times they make the jet orifice very small to save gas, but it can cause clogging issues. Bad enough that we have to suffer with Ethanol in the fuel!
Don’t buy gas with ethanol for use in lawnmowers. Problem solved.
Thank you Steve for sharing your knowledge, I followed your instructions and was able to start the lawnmower in less that a full pull .
From Dallas TX
Excellent!
As much as I like the B & S 500 E Engine, I'd like to replace the Sponge Rubber Air Filter with a Paper one..does B & S sell these ?. A part number would be wonderful...
Great video & explanation of the carburetor jet issue & its repair!
I assume Briggs & Stratton intended for the carburetor jet size to be as small as for the jet shown in the video, because carburetors are very carefully designed, & precisely made things. Even so, design & manufacturing errors are possible, & maybe an error (jet size too small) was made by Briggs & Stratton regarding the carburetor jet size (for these plastic carburetors).
Regardless, the engine seemed to run ok after Steve cleaned the carburetor the first time (before he enlarged the jet size) until the jet clogged.
I wonder if installing an in line fuel filter would have solved the carburetor jet issue, instead of enlarging the jet size?
Thought I had tried everything until I watched this video! Cleaned the cartridge and it started right up! I wouldn't have tried taking the cartridge out if I hadn't watched this video! Time for a Corona to get its lime!!
Right on....
Stevie my boy you NAILED it !!!!!!! Thanks from Brick NJ
You're Welcome...
Hey also ocean county nj!
Thank you!!
I kept saying something was clogged and after watching this video, I disassembled the carb and pulled the cartridge out. I tried to spray carb cleaner and the jet was clogged. I used a torch tip file to open the jet and sprayed carb cleaner through the cartridge and it blew through the jet!!
Reassembled and she started right up!!
Thanks again!!
Great job!
I have a brand new b&a 875exi engine 190cc, with the plastic carburetor. It runs horrible! You said you haven't heard from the lady over a month. Fix the problem? Please let me know! I ordered a new carburetor for it. Will check it with drill bit too.
Top job Steve- I appreciate your persistence and clarity - absolutely solved a very frustrating problem for me. Had to get the glasses out to deal with those pesky little drills but it was worth it. Started first pull on re-assembly and hasn't missed a beat. Cheers and have another cold beer - You deserve it!
Excellent!
Sweet! Drilling the main jet out with 0.5mm bit worked for me.
Thanks for instructional video on this!
Great to hear!
Just had this exact problem. Smallest jet ever 😝
Thanks Steve, you’re one of the best!
You're Welcome...
Hey Steve, You're my go-to guy for lawn mowers and doing a great job, keep it up. I'm a little off-topic here, but it seems as good a place as any to ask a question. I live in FL and have a LOT of sand and dust problems that quickly clog up an air filter on the mowers. Right now, I have the standard 6.5hp self propelled mower with a B&S engine (uses the rectangular filter, probably not the latest) and it does the best as far as filter changes go. Then I have a Toro Recycler with the small oblong filter that is a pain. Don't laugh, but I have thought many times about mounting a larger filter assy somewhere and running a hose to the carb. Is there anything out there that already fits these engines made for a heavy dusty environment? Also, I have spare carbs for both engines and the flange side where the air filter housing attaches has the same bore and bolt spacing. Do you know of a simple plastic or aluminum flange that would bolt up and allow a round hose to connect to the intake? I've looked a few times and come up empty. I've found larger ones, but nothing that size. If anyone might know, you would. Thanks for any help.
Have spark. Checked valves and other areas. The mower wont even try to run
With some starting fluid. I have the 300e engine 125cc. I guess off with the carb. Buy the way I only run regular gas and run it out of gas before going back into the garage.
Update. Took varb off and yes the jet was plugged. Cleand it tank and every thing else. Shoot some go juce and the dam thing still wont start.... HELP...
Am so glad I stumbled upon your channel.....I used your video to fix a lawnmower that was given to me! It's not often you find a businessman with your integrity! Keep up the great work! Hope you and your family stay safe and healthy
Thank You...
Steve, This is the type of carburetor I have on a two year mower. I was able to clean it following your directions with carburetor cleaner and get the lawnmower running again on the first pull. Thank you! You may want to mention please wear safety goggles and gloves when using carburetor cleaner. Also, I had to review the video to make sure that I put the plastic cartridge back in the correct direction. The screws holding the air cleaner cover were interesting to line up again. Two different sizes slightly different, and another size for the plastic "bowl" cover.
The different sizes are indeed a pain! I am a 1/4 inch drive socket set aficianado so it wasn't a problem for me, but ... why did they use two different sizes?
I have been trying to fix my own mower for 3 weeks. Same deal....plastic carburetor had that tiny hole clogged. I didnt have any wire to clear it, but your twist tie idea was genius! Cleaned it and it fired up off the first pull! Thank you so much.....especially for the recommendation for the giant beer! Cheers!
You're Welcome...
Hi Steve . Im Confused . Can you Please tell me The EXACT Size of Drill Bit I Need To Drill out My Jet .
And is it COLOR CODED .. TO IDENTIFY IT EASIER ..
Thank You Steve 👍
Steve got to thank you. I tried your mixture on my honda and it works great man. Thanks for sharing.
You're Welcome...
Mine ran great for like 5 years, it did surge a bit but ran good, this summer it wouldnt run at all without closing off the intake, then it would run for about 10 minutes.
Pulled the carb, cleaned it all up, warbled out the jet with a .5mm bit, thanks to 3D Printing or I would have had to make a run to the hardware store.
Runs better then ever....
Thank you so much for your instructions and your encouragement. Fired up first time and every time, sweet.
Great job!
Thanks Steve... and cheers!! Pulled the carburetor and cleaned it following your instructions. Started on the first pull. Great videos!
Great to hear!
I know I’m 3 years late to the party but I need to tell you thank you for this video. You saved me hundreds on a new mower. I was at my last straw. I cleaned my carb 3 times, the gas tank and fuel lines twice, new plug and air filter too! Could not get it to stay running. I mowed my entire lawn by spraying starter fluid at the intake the whole time! I never knew that little white jet housing could come out. Sure enough that “secondary” outlet was clogged. Sprayed it, used my pin vise to loosen the clog, sprayed it again and reinstalled. Now my mower starts on the first try (no ether) and runs like a champ! Thanks again, Sir!!!
Right on Brady! You're Welcome...
I also have a Briggs and Scrap 'em with a plastic carburetor that "hunted and surged" from the first day I bought it new. I removed the carburetor and blew out all the orifices with carb cleaner and now it'll start and die. Once I get it started, I have to continuously pump the primer button until the engine warms up enough to roughly run on it's own. The next tool I'm going to use on mine is a BFH. Update: reamed out the main jet with a 0.020 drill bit. The mower now starts on the first or second pull and the "hunting and surging" is gone.
I think the problem I've had repairing my mower is that I don't drink beer.
Thank you so much for your detailed tutorial. My 2 year old Lawn Mower would start but not stay running. After following your directions its running again. I found and removed the deposits on the "jet" opening of the cartridge and the "needle" under the float. Thanks so much for sharing your knowledge.
You're Welcome...
I'm saving money! !!!! Cheers.👍 steve😆
Next time I'll get myself a Colt 45 and also just, hey I was broke to get carb cleaner but did ok with normal degreaser and person blow than machine. Did fine just sayin
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, you've explained that on some the hole at the bottom does not blow out the front and on some it does.
Coincidentally in my case 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 when they refuse to work right (engine turns on but sputter from rich mixture), 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?
By the way, it was this video that got me through the first time around about five years back.
Thanks
Thank you Steve! I've got a Troy-Bilt with a Briggs engine and the plastic carburetor. For a while I got by by removing the carburetor and merely sloshing it around in a can of gasoline. Then the frequency and character of the problems increased. Most recently I got the oscillating engine speed. That's a nightmare. I ordered a micro drill set from Amazon because I wanted a next day solution. I also order the set with the HSS drills. That left me with a smallest drill size of .6 mm but I decided to go with that because I didn't want to fool around with stainless steel drills. I followed all of your instructions after very carefully enlarging the main jet to .6 mm. It started on the first pull and ran smoothly. I could have never imagined such a simple solution... but it worked! Thanks again.
You're Welcome...
@@StevesSmallEngineSaloon I didn't see the set of drills you recommended until after I ordered another one. Oh well. Your recommendation there was better, too.
I have one of these and it almost sprays gas while running.
Thank you Steve. I had 2 Toro B110 lawnmowers (from Lowes) sitting outside for the last two years. Circa 2018, 2019. Both worked for about 2 months each and then refused to start. I used your repair method on both and now both running very well. Two pulls to start them. Indeed, it was that interior jet that was the issue. I used the twist tie and several squirts of carb cleaner. Now... I need to watch your string trimmer videos and repair the 3 I have that are inoperable. Toasting your health with an Obsidian Stout. Cheers my friend...
Right on Dan! Thank You...
Did you fix all 3?!
Steve Great video as always. You really explain everything well. I thought I would get out of this easy by dropping the float bowl and cleaning the one visible jet. It ran but there was still a blockage so I watched your video broke carb down, cleaned all openings and it runs great.
I use the ends of guitar strings to clean jets. They work great and come in all gauges. You throw them anyway when you restring a guitar. Thanks again. Gerry
Hi Steve. Great video. Thanks. Question: I have a Troy-Bilt TB110 Briggs Engine with the same plastic carb. I'm having a a surge problem. New Carb, New Spark Plug, New Air filter, Cleaned the fuel tank and made sure the screen inside tank was clear, brand new 93 octane gasoline Adjusted the idle to 3200 RPM'S. I'm still getting a slight surge. It is better but still there. Should I open up the jet as you did? Any Ideas? Thanks. DJ
Hi Steve...... throw away a carb?? No way! I'm right there with you. And thanks to THIS video, I fixed my Briggs 500E in less than five minutes. I've no idea WHAT is actually causing these brass jets to clog up, but the .020" drill bit I cleaned it out with SOLVED the problem. (I've also STOPPED using Ethanol-laced fuel in my yard equipment and use Ethanol-Free instead... figuring its the excessive varnish in the Ethanol that plugging the jet). THANKS AGAIN for your GREAT video Steve! :)
Nice work!
@@StevesSmallEngineSaloon AFTER I sent this, I went deeper into your other video on the Stihl Motomix and the contents of the fuel mixtures. Then I felt kinda bad I wrote about the ethanol... evidently, THAT's not the problem. But running the ethanol-free fuel seems to be a little better anyway. That $28 a gallon for the GOOD stuff is too steep for me. I go thru a lot of fuel (big yard and lotta tools).... for a savings of >$23 a gallon, I'll clean out the jets every now and then.
Thank you!!! I watched a dozen other videos and disassembled and cleaned this carb. about 4 times. Watched your video and drilled out the jet. It started on the first crank.
Great job!
Thank you Steve, used your idea and the mower works now. Thank you so much. I almost got a new mower but not now.
Fantastic!
the quality, durability of lawn equipment gets worse every year while the price, even for the cheaper models, is steadily rising. This whole process, the not taking care of things, not bothering to fix it, the throwaway mentality is a clear indicator that the US dollar doesn't hold much value or worth when making purchases and It all starts with the mindset that nothing is worth fixing or taking care of. As long as it looks all pretty and shiny on the outside!
i brought a briggs powered husqvarna mower back in apr 2017. i was used daily for 4 years and it NEVER had any form of fuel problem. its only today (april 2023) that the carb has suffered a blockage. a new genuine cartridge jet is on order. they are less than £10
This was awesome! I was able to fix my pressure washer based on this video. I do question Steve's choice in beer but that's another subject. Thanks!
Fair enough!
Great video! managed to fix lawnmower quickly and always love to learn a new skill.
great attitude to repairing and not replacing parts unnecessarily, we need more of this! cheers!
Thanks 👍
