I appreciate you! I’ve only had my mower for 1.5 years and was getting frustrated and was ready to take it to have someone repair it. You have a gift in explaining the correct process on what to look for, and have a great personality. I was able to fix my mower in one try and it’s working better than ever. I’m not a great handyman, but you’ve given me more confidence that I can do things myself! Thank you sir!
Thank you for the wonderfully kind feedback. Congrats on your fix!
This gives me hope. 😂
well done video....
Scott Wahl, thank you sir!
I just want to thank you. You video allowed me to strip down my mower, clean and fix the carburetor and started first go. I also washed out the fuel tank and put in a new air filter. You are a legend.
Thank you Jennifer, I am humbled by your words. Congrats on getting your mower going again!
THANK YOU! I have never fixed any motorized thing before. After watching your two videos I attempted to fix my lawnmower that would not keep running after squirting starting fluid in the carb. I followed your pointers and after putting everything back together it ran like a champ.
janice, well done and congrats to you on the success! thanks for taking the time to comment
Cool
Seriously I want to buy you a beer. I was frustrated for 2 days with the fucking lawnmower until I calmed down and started browsing came across your video. I didn't do the rebuild because my lawn mower is 2 years old and it would not start after a full tune up.I got the jet out and cleared it from the carb and bammm..... one pull and shit fires right up. This gave me a huge insight on carburetor for lawn mowers and it made my night. Thanks for sharing
Iggy One, lol, thanks for the comment and I am serious glad you got it running again. These things are tricky if don't know they come apart like that!
Really appreciate the video and I checked all this but upon reassembly I noticed that the throttle cable on mine wasn't moving the carbie levers at all. If I manually move the lever on the back of the engine that controls the wire directly on the carbie it works fine so my issue appears to be the cable isn't moving lever properly. Ran out of time to investigate further but I learnt a lot so thanks!!!
Maan!Thank you for making this video. Had the same problem and now it's working great. If you were close, I'd buy you a beer or 12. Good job!
larios956, you are welcome my friend. Thanks for taking the time to comment and congrats on your success!
I agree. This is what I needed to save my sanity. It worked perfect! Thank you so much for a perfect tutorial.
At 6:40 minutes the white plastic piece being remove is called a cartage and can be replaced with a new cartage. Also the cartage comes apart, two pieces. They more or less pull apart, might need a very small flat blade screwdriver to pry apart. Both pieces can be cleaned and one of the two parts has jets which should be cleaned. These jets usually clog due to using old gas, contaminated /dirty fuel or fuel varnish / corrosion build-up.
Your video is spot on. I had the exact same problem and the mower was fixed in short order. Thanks for the information.
Thank you! Excellent presentation! You helped me a lot. Greetings form Poland:)
Andrzej, thank you for taking the time to comment and greetings from Las Vegas
It`s a really detailed tutorial... We have the same "piece of plastic" on our Toro mower. Can you tell whether this carby can be adjusted or cleaned only? There is no doubt, the engine runs on very rich mix... To fix this, we have to change petrol/air ratio. It can be done easy on metal carburetors by special screws. This plastic one do3esn`t have any visible screws. So, how to change the ratio?... Thank you
As far as I know all the mixture and metering adjustments are long gone on these little carbs. Sometimes you can adjust carbs on 2-cycle engines, but the 4 strokes....that ability is gone.
@@jcx2bby Yes, you are right. I mixed up two and four cycles engines. Well... but is there any way to fix in case if the mixture is too rich (a spark plug is always covered with carbon)? Or just carb replacement? I`m really confused. Thank you
Don't work over grass...or have a magnet handy. On the little white tubes I used one of those grocery tie raps by gently peeling back the paper to expose the thin wire, to be used for getting the green crud off the little brass orifices in their respective tubes (the little white tubes), including the two slipped one into the other. I blew out all the tiny holes with a little red tube on the nozzle of my starting ether. The bigger holes, a new q-tip gently inserted and rotated was effective. Any spraying, keep any tubes perpendicular to face and wear safety goggles, really! I prefer the ether since it is safer, I think, than the carb cleaner. If you disturb the giant o-ring of the bottom bowl be careful in reassembling it since the rubber will appear like it grew and now does not want to fit. And don't forget the little white plastic adapter ring that squeezes the o-ring against the rear of the carb tube going into engine hole. That's an easy miss. Thanks. again.
Get rid of the fuel in the tank. If the mower spent it's time outside, there most likely will be water in the tank. And the fuel may be old. Just good habit.😊
Very helpful
THANK YOU!!! I've been fighting my lawnmower for 2 days. Excellent video, even better explanation.
@@k_hunt awesome. Appreciate the comment
Thanks for the in depth explanation and take apart process
Thanks. Absolutely what I needed to know before I start doing my mower.
@@MrDaveozau glad to help. Good luck
Thank you so much! U saved me a bunch of money! SWF and I try and fix everything myself within reason. My troybilt wouldn't start and after I did everything on your video. It started!!! Thanks again. Kim
Great job Kim!
Great video, really clear, especially liked the clear showing of the throttle arms and auto choke lever, that's something lots of videos skim over.
Thank you
Thank you! This worked perfectly
Sweet, glad I could help!
I can't thank you enough! I've never repaired a lawn mower before, but with your help was able to get my mower up and running again. 👏👏👏
Sondra Benson, awesome! Thanks for taking the time to comment and subscribe if you haven't already.
Thank you for this! It's raining here in Westchester, NY. I've done everything but no luck. So now I'm going to dive in for the first time. Wish me luck! 😂
You got this brother!
Hi. Great video. Only problem I found with mine is the carb flap doesn't swing open and close. Any advice
Good video. Repaired a couple of these types myself and your right, you may have to disassemble a couple times to get it right. So a good rule of thumb is to take your time and clean it good and it will crank first pull.
Yessir
Great job man ! It was very informative and easy to follow .. I’m sure you helped a lot of people.. thanks !!!!
Thank you sir
Excellent presentation! I put in a new carburetor in a Briggs and Stratton ex 550. The mower was surging and backfiring. Do the jets need to be checked on a new carburetor? Any other advice? Thank you.
On a new carb they should be fine. I'd just double check the bowl bolt is tight and then give it a rip.
You are a life saver thank you.
Glad to have helped
Thanks for such a great explanation. Appreciate you.
And thank you for the kind feedback.
Wow is simple I have not like the plastic carburetor I work on small eng for 20 years
Once you see how it works, yes, pretty simple
Great video, thanks! Another mower saved, just needed to clear out two jets.
Nice work!
1:56 Do the same test after screwing the carburetor back together. Right side up, you should be able to blow air into it. Up side down, you should not. A quick way to check whether it was put back together properly.
JeffTheHokie, it's an unpleasant way to test them, but effective!
Gary R Wilkie
Very helpful, good video. Thank you.
Thanks Gary
Thank you mower is working perfectly now 😊
Hooray!
Excellent breakdown - I have a very similar 550 and thanks to this guide I wasn't surprised by pieces falling out and got my mower running again in just an hour or two, never having done engine work before. I found it much easier to access by putting up on a workbench if you have one around.
Camera focus tip: fill up the screen as much as you can with a closer background like your hand and it will help the camera figure out where it's supposed to focus sooner.
All said, thanks for taking the time and effort to put this together!
Thanks for the tip Ryan, I really had no idea the camera was out of focus until I went to put this online. On the tiny veiwfinder (it's an old-school point/shoot) it looked like it was in focus. But obviously it was a little fuzzy.
Thanks for the comment and congrats on getting your mower running again.
Can air works good 😁
Wow, Help all the way out to Australia! I have a locally made Victa mower with the same Briggs & Stratton engine with the same problem. It is 19 years old and this is the first problem ever. Thanks to your first class youtube tutorial I fixed it for no cost. Most of the car jets were partially blocked with 19 years of accumulated crud. There was some black foam jamming the needle and seat almost shut. All fixed now thanks to your help from Hawaii and youtube. Thanks for posting this very helpful clip.
Hey Gary, thanks for taking the time to post this! Congrats on the fix, although I am no longer in Hawaii, it's nice to see how far and wide this little video has traveled over time. Cheers
After I cleaned the jet out and put it all back together I forgot that I had disconnected the spark plug wire and thought that it wasn't working. lol. Thank you for the video!
Awesome. It worked. Many thanks
You're very welcome. Thanks for taking the time to comment
Thank you so much for this thorough explanation. This got my mower running!
Outstanding!
Thank you for doing this video! I was getting so frustrated with my lawn mower not working properly and hard to start…I was actually on the Home Depot website looking to go spend $500 for a new mower. But then I thought to check TH-cam and came across your video! Your instructions made it so simple!! Now about 45 minutes later.…The lawn mower started right up and my son is out mowing the yard now!
I don't know what's more awesome, the fact you got your mower going, of the fact your son is mowing the lawn!
Just fixed today. You are king. Getting all back together after stripping it all down and then it working was so satisfying. 👍
Glad to have helped. Congratulations!
This guy sounds a lot like Dirty Harry
Beat me to it.
Thanks
Excellent job Thank You
Thanks!
I want to thank the gentlemen that did part one and part to , of how to fix a lawn mower that wouldn't start. I a woman that had no idea how to fix a,lawn mower, you helped me soooo much I did everythimg you told me to do and when I was done , it started right up, I was so proud of myself thank you so much. Tytyty.
Denice, you are most welcome, I'm glad I could help you. My inspiration for my video method comes from my mom who was never sure of these things either. Your comment is affirmation that I am striking the right chord so thank you for taking the time to comment
Woohoo 🙌🏽. Thank you so much for your 2 part videos instructions. I am a widow and 61 years old my husband did all the yard work before he got sick and passed on. I had no one to help me; so me being me I searched TH-cam and I found your videos because my lawnmower wouldn’t start for over a year now. 🙏🏻😊👍🏻
Thanks for commenting Crystal. Congratulations on finding the way to fix this stuff yourself! TH-cam has been a godsend to the DIY minded.
Great video! I watched another guy's video first that didn't show how to remove the jets. Didn't work. I watched your comprehensive video, took out the jets and cleaned out the little tubes and my mower fired up with the first pull after I out it together again.
You should also pull that center piece. That white plastic piece. Use a screwdriver to help gently separate the emolstiin tube.once apart. You will discover three tiny holes. They must be clear of any obstruction. Also push out the metal ball. Don't loose it m spray carb cleaner through those bleeder holes. Reasemble it
One more grateful person here - I was doing a tune-up and must have got some oil in the carburetor when I inverted it to drain it. The local repair shop was backed up for 2 weeks so reluctantly (since I'm not super handy) I followed your video. Took me twice as long since I was double checking every step - but it started up right away. I have finally overcome my fear of the internal workings of a lawnmower. Thanks so much.
Awesome! Thank you for sharing this with me, I love hearing other folks success
Thanks. Took my carb apart twice tonight to clean and fix my mower. The little round shiny metal part on the bottom of the carb space had come out of its place and was evidently rattling around. Your video showed me where it belonged and also how to clean everything. The last few times mowing it was surging. Yesterday, it would only run for 2 seconds at a time. Now, it is running like a top. Thank you very much. Now I need to watch a video about sharpening the blades.
Thank you, thank you, thank you.
that shiny disk mines keeps falling out
First time lawn mower carb. fix. WOW!!!!! Your video did it for me.... THANK YOU
Woot! Congrats man
Good presentation. Effective in presenting fixing small parts of small engine carburetors with explanation.
Thank you Tom, I sincerely appreciate the feedback and kind words.
Lol man I also do the same thing with the seeing pin thingy. Not I have torch tip cleaners
Thanks so much! It was just what I needed. Your presentation is very clear and it's important for me because I'm French and my English is not very good. But I have understood all of your explanation!
Merci beaucoup! I am truly happy to have been able to help.
This was viewed may 9th. Great job explaining everything. Thank you.
Thanks mate from Humpty Doo NT Australia 🇦🇺 👍 love your work
Thanks for telling me to “man up”. I needed that reminder. Had this mower sitting in storage for 7+ years used only a couple times. When my electric died, broke out this one and it didn’t start. Followed your tutorial and it’s running like a champ. Thanks!
Nice work!
I have done this several times and eventually the carburetor gets clogged up again. I have a running rotation of cleaned up carburetors and some new installs to keep things going. However, I had a brain fart and there is a new red circular O ring in a new carb kit (other one is obvious). I noticed I had a hard plastic circular and an older black O ring back to back for some reason, maybe in wrong order or place on the mower side where we are placing carburetor back on. If that makes sense, tell me what belongs or what the red o-ring needs to replace or maybe I even have 2 white plastic rings from previous installs?
Just buy new jets if you cant get that unblocked
thank you for posting. at 3:42, what's the name & function of that round disk of what appears to be metal foil, approx 10mm in diameter, kinda east - northeast from the tip of your left index finger ?
I have a 650EX series....getting a spark, good compression, cleaned carb. Will not come close to starting when starting fluid sprayed down open butterfly. Any suggestions?
Bread twist tie wire works well for the brass jets.
Often,you can find the same material in spool form in the garden center of your home supply store that's used to tie up plants.
Another pro-tip! Thank you for posting that.
Thank you so much for the video and taking the time to do it. I had gotten 90% of the way b4 the video. But the last parts about cleaning the intake (White Plastic item) was spot on. I did it and got the beast back to working! Thanks for posting!!!! -RR
You wouldn't have to take it apart 2 or 3 times if you clean it right the first time. You removed the jet assembly to clean with a sewing needle, you should have removed the outer assembly to get to the orifices inside the center (main) jet. Soak everything in carb cleaner for about 20 minutes, then reassemble. One time!
Just an FYI. There is one more disassembly step you can do with that innermost white carb assembly (with the stacks). The center 'stack' can be lifted/pryed off, exposing a few more interior jets to clean out. Other vids on here describe it.
If I'm going this far I think I'd try to clean out as much as possible the first time.
Thanks for the video.
a user, I had no idea there was more to take apart. thank you for the tip.
I just took mine apart for cleaning. First time I've opened up one of these plastic carbs. That center white stack was a real bear to pull off (as was my gas line). Others have recommended prying it off with a screwdriver but that seemed like an easy way to break it. I ended up repeatedly twisting it slightly back and forth while pulling very hard on it. There were three holes in there, one of which had some crud.
The sewing needle idea worked great. I actually used a pin.
Amazing that after 7 years this video is still yielding dividends. You helped me salvage my mower. Thank you so much. For every grace that is administered there was a price paid by someone. Grace is not cheap just because it's free. Thanks again!
Thank you
My carb had a tiny metal circle disc loose inside carb any idea? Looks like it sits in the bottom
I use the ultra sonic cleaner but I don’t heat it on plastic anything
Carbs are ok but dirty air fines will destroy the engine IF not clean every other use
Perfect video so easy to follow fixed my briggs stratton 550ex mower! Thanks
I found heaps of water in the mower fuel tank🤢 Need to dry it in the sun. Petrol doesnt clean the water out
Thanks.
You're welcome
The corrosion you are talking about is not from rain water on engine but fuel is breaking down ethanol so turns to water
Best instructions for fixing a lawnmower I have seen, thank you.
Thank you
One benefit to these new plastic carburetors is there are plenty of free mowers sitting by the curb on garbage day. People throw these out because the carb is clogged, and a 15-minute no-purchase repair will fix them.
JeffTheHokie, amen brother.
7 years later, I just did it as you shown. Fixed ! I hope the little heart is doing well 🙂
Great job! Yes, the little girl is now 8...time flies. Thanks for commenting
With a carburetor spray used the cauciuc gaskets deforme.
I found that I need to take the jet assembly apart. The middle white plastic rod has three holes. All of mine were gunked shut. I cleaned them out, reassambled the machine and viola. Thank you for this video. Tool less than an hour.
Woot!
that white plastic piece comes apart and theres little side jets that must be cleaned
Thanks man
You're welcome
at 9:39, dude, i swept up the perfect jet brush in my basement last night and thew it on my work bench.
Lol
Excellent presentation
Glad you liked it, thank you
That was right on time. I was frustrated mower wouldn't start. Saw your video. Fix my carb and finished the lawn just as it got dark. Thanks
Dude, I'm glad the video helped you and I appreciate your comment. Great job!
Thank you!!!!! :-) !!!!! I really appreciate the help!! You had every step so well explained. The only thing I had to look elsewhere for was how to move the fuel line clamp. I was starting at the BASIC level and still managed to do it with your help. Thank you!
I'm glad you figured it out and I am vicariously proud of you. Thanks for commenting on my video
Excellent vid, thank you!
Thank you for the comment
Excellent. Thank you. Now I know how to fix mine!
My Brother… fixed my mower watching your videos! Kudos!
Happy to have helped!
Thanks for the clear and informative DIY video. Restricted jets were causing hard starts and fluctuating idle. 🤙🏽🤙🏽🤙🏽🤙🏽🤙🏽
You're welcome, thanks for commenting
Hey my friend I just finished doing this to a toro mower and it fired up first pull. Great video with fantastic instructions. Thank you very very much.
Awesome man, thanks for the compliment and congrats on your success
Thank You so much my mower runs great after watching your video.Great job sir!!!!!!!!!🔥
Thanks Will, glad your mower is up and going again
This was very helpful! I did exactly this and it worked like a charm, thanks!!!
Hey Alex, I'm glad it helped you. Thanks for commenting.
on the white emulsion tube that one jet ... does it even have a hole?
Nice work and easy presentation. Very relaxed. I have the 550 series which has the single spring. Would you know that spring part number? Also, is the diaphragm part numbered 795083? Please advise, and thanks in advance for your help.
Scotty, I don't know all the part numbers but if you go to the Briggs and Stratton website and put in your engine's Model/Type code, it will bring up a parts breakdown that will give you every number you ever wanted.
shop.briggsandstratton.com/us/en/repair-parts
Diaphragm? None on this series carb that I recall.
GREAT video. had followed 2 others with no success. found yours and found the detail i needed that was missing in others. found out where that little silver disc goes in bowl by looking at your pics.THANK YOU.
Awesome, I am glad you found my video and that it had what you needed. Thanks for your comment
There’s something extremely satisfying about getting a non-running machine going again. After opening mine up, the needle was missing. Replacement carb #593261 $9 on Amazon.
I 100% concur. Great work finding your issue!
Definitely a good help to watch this before first time repair. Mine went perfectly - found a tiny bit of debris seated into the intake port.
Glad it helped and thank you for the comment.
22 March 22,
Thank you for the video. You saved me alot of money. Question??? How often should I do this???
I only do it if it needs it. As in, it's not running
Exactly what I needed to fix that annoying running problem. Now running smooth, like new. Thank you. Narragansett Bay
No problem, glad you found the video helpful!
Thanks man. I have the 525ex, but same build. Didn't have starter fluid so dropped some fuel in the carb, it started right up. I used old fuel so think the fuel/air ratio was wack
Good luck with it and thanks for the comment
This may be from 5 years ago, but I have this same exact mower that was abandoned in a shed. And was able to basically get it for free! And I've never was able to get the original carb to really ever run right. But I bought a new carb off Amazon but I think I have the wrong jet Inside my carb. Because it surges up and down and I didn't realize that the carb is not the same part # as this carb. But thanks to you now I know what size jet to get for my carb! Should make it run great afterwards In my opinion.
Awesome, I am pulling for you, hope you get it sorted out soon.
It's August of 2021 and your video helped me revive a throwaway in excellent shape. I need a power mower for the yard again. Thanks! ...
Awesome! I am happy to hear this. Congrats on the fix!
your video was right on, drove 20 mins., in a half hour my friends mower was clean and working... thanks to your video... ps I mowed his lawn too
Lol right on Chris!
