Thank you so much for this video! I removed the bolt on the carbonator bowl, looked through the side holes, and it looked fine. I decided to run a straightened plastic coated paper clip through the hole and a little bit of crud came out despite looking good. I then sprayed carb cleaner in the top hole followed by WD40. Put everything back together, primed, it started and stayed running. Woohoo! Thanks again!

My friend. I just watched your video. And removed the bolt. Cleaned it, and put it back. Bam!! She purrs like new!! I ran it for 15 minutes 😊. Typically I’d be at Home Depot buying a new one. Mine is 20 years old. Never cleaned before. Thanks again for your tips. My wife thanks you too!!!!
This video was very helpful. It started right up and kept running and saved me a repair of several hundred dollars. I'm not terribly mechanically inclined so I'm amazed that it appears to have worked but we will see.
Awesome video, thanks. Great, friendly presentation.
Thank you, thank you, thank you for this video! I changed everything else for maintenance purposes but this did the trick! My lawnmower is now running at FULL throttle!... Now if I can only get that first cut in before the predicted thunderstorms, lol Again, thanks!
THANK YOU. The 7:45 min video is pure GOLD. Fix my lawn mower in 5 minutes.

Thats what I was looking for, an easy diagnosis procedure for these particular symptoms. I started it, kept pumping the primer button, and it kept going after about 15 seconds. It's running enough to finish but surging, so I think I have to pull the carb bowl before mowing anything major. THANKS
Excellent video with great easy to understand info. Thanks for sharing.
Excellent detailed video!
Thanks! After a complete carburetor rebuild which did not fix the problem, I came here and found the info I needed about the float bowl bolt. Cleaned that out completely and voila...mower runs perfectly again.

That is a terrific video...you hit all the details in an understandable fashion. I could run the wire through the side holes but not the top hole...not sure what to use to open up that top hole....the wire won't push through. Squirted WD-40 through side holes and some did flow out from the top but did not fully open.
Great video explanation. Worked a treat, got to buy some new o rings and gaskets but that's it. Thanks and a big thumbs up.
Neal B Glad you enjoyed it!
My self-propelled push mower would start briefly and die. I changed the oil (needed it anyway), air filter was fairly new, put in new spark plug, poured out the gas and put in fresh, etc... I was getting disgusted with it, sweating, covered in mosquito spray, hot (Texas) and about to give up. THEN, I watched this video. This mower has taught me plenty, but I was leery about attempting. The way you walked through it gave me the confidence to give it a shot, nothing to lose, right? I gathered up tools I thought might do it, had to improvise with a tiny clamp that belonged to my dad, etc... Anyway, I took it apart, it didn't look too bad, not gummy, but there was approx 5 tiny specks in the bowl, wasn't sure if it fell in on removal actually, put some wire thru the tiny holes, sprayed with the WD40, all that you showed. I put it all back and my hopes were not high. I started it, it died, I started it again, AND it DIDN'T die!!!!!!! I was delighted, woo hoo! I couldn't believe it actually worked. Thank you so much for your great video and how you keep it simple for greenhorns like me. Thank you, thank you, thank you, sir!!!!

THANK YOU!!! I did this the first time and it still didn't work, but after reading through your comments of keep doing it several times, that once may not be enough...it started and stayed going!!! I discovered that there was little flecks of debris still attached to the float that kept blocking the hole even after I cleaned it! Great advice!!

Great video! My mower is acting up so I'll try this out. I laughed so hard at "this is your float, no need to touch it" whilst you're fingering it up and down. 😂😂😂
Glad you enjoyed the video Kenny! Be sure to check out my wide range of videos, and share my channel with many others. Thanks!
with that air filter ,light test it hold it up to the sun if you cant see thru it replace it . its only a 7-9$ filter.
i recommend using a torch tip cleaner from harbor freight to clean your fuel metering bolts ,since a lot of oxidation wont be remove with a wire that isn't almost the same size as the metering hole.
Worked like a champ, there was tons of sediment in the bowl! I'll have to install an inline fuel filter!
Lakedog Great to hear! Remember, old fuel sitting inside the carb/bowl can also gum things up.
very good...
Thank you!
SIMPLEST FIX: No need to remove carburetor, just put carburetor cleaner in the tank. Details below.
My mower sat for 18 months with 1/2 full tank (does have fuel stabilizer in it). Symptoms were same as yours except my motor wouldn't start at all until I got some starting fluid. My fix was to top off the tank with fresh fuel and add "Fuel Injector & Carburetor Cleaner" from Walmart (Supertech, 6oz treats 21 gallons). I estimate I used about 3-4 times more than you're supposed to. After adding the carb cleaner, I started the motor several times with starting fluid but no improvement. I let it sit for 24 hours and the next day, with the help of some starting fluid (ether), it cranked up and ran without stopping. I did manually push the throttle open to get the rpms up until it got warm.
You may not be so lucky, but its worth a try. I have a Briggs&Stratton 500E.
UPDATE: As it turns out, I have a SECOND lawn mower that also would NOT start after sitting. This time it was not so easy. I tried the "Carb Cleaner in the old fuel" trick for several days. I ended up having to lean the mower over and dump out the old fuel completely. With a completely empty tank, I put in the Walmart Carb Cleaner and FRESH FUEL JUST PURCHASED into the tank. Again, I had to let it sit over night, but with the help of the Starting Fluid (Ether) and pushing the red primer button a bunch of times, I got it going. That's TWO times I fixed this problem without removing the Carburetor. Takes a little more time, but removing the carb is no fun.
and yet another great video, electronics and, oh this is the More part. thanks mk
snaprollinpitts Thanks, and yes, this is the "More" part of my channel. The "More" videos appeal to a larger audience, and have done extremely well for me. Unfortunately there is only a very small % of viewers into electronic circuits, so the "More" part of my channel will always be a big part of my channel unless there is some serious sharing by my viewers of my electronics videos to get the view count up. You have to go where the views are.
electronicsNmore I'm cool with that!!!
worked for me

Good to hear! Please share my channel with others and rate Thumbs Up. Thanks
Carburator cleaner would be way better then WD-40 for cleaning out debris. Great video otherwise. Installing fuel filter is wise suggestion. Should look into that.
WD works great, but yes, carb cleaner even better. 😀
When you have the bowl off, be sure to observe whether there is any water droplets in the bottom, mixed in with the gas. This moisture will also prevent the engine from running properly.
True. Thanks for watching!
Use air or carb cleaner to clean the bolt
well I need to know is it a bad carb or ignition module..? How do know if it is a carb or bad ignition mod...?
for clamping I have hose clamping pliers but I prefer my long nose vise grips that I put rubber hose on both jaws and squeeze and lock shut the gas line. Just a thought
Ed Ginsberg Yep. Great idea. I forgot all about that.
Thanks For Watching!
+Ed Ginsberg That idea also works for pinching brake lines while repairing a caliper.
Good Video. Thanks. Question: What is the tool name of the fuel line crimper (do-hickie) you used? Looks like a very simple practical tool. Thanks.
Hi there. Very inexpensive for the set. Hose pinch pliers.

my riding mower had similar problems ... and i ended up replacing ignition mod and problem was fixed...
You have a lot of troubleshooting to do. Unfortunately I can only answer a viewer once or twice. I have over 350 videos with people asking questions. Good luck
Thanks ...
I took this off my Honda yesterday and the bolt had no holes.
Mine had no hole either. Mine is toro ez stow with Briggs. After removing the brass bolt there is only one center hole. I could not get the cup to release.
Is it the same if you have a non prime mower? Troy built?
Same for all the small gas engines I've worked on.
Curious, You "Never" Once, considered the Spark -Plug, to be a Major Problem......On my one ( 30 ) Year Toro Lawn-Mower, I discovered the Plug was "Bad" & purchased a New One. Than I pulled on it, with only ( 1 ) Pull, it works Fine.......! Now my Second Toro has the Problem, that you discuss in your Video.....! I plan on, taking the Necessary Steps & have already Purchased a New Spark Plug & New Filter.......I paid $ 80.00 Dollars for a Back-Up Mower, due to my First Mower, which is getting old. But , one thing for Sure, Toro makes a Good Mower.......!
Why? Because I was showing the most common cause(98%). Thanks for watching!
Were can i purchase a fuel filter for my briggs and Stratton mower ??
Hi James. Home Depot, Lowes, or at the link below. Thanks for watching!

Aha, suddenly reminded of the old history of WD40. 40 attempts to get the water displacing formula worked out.
TheOldmankk I think WD-40 is nothing more than a light weight oil mixed with mineral spirits.
to make sure its not the air filter just try to start it without the filter in a clean area if it starts its the filter if not...wile you get it
+Cameron Hud
Hi Cameron. Sorry I took a while. Every so often I miss a few comments. You can take off the filter, but some mowers will not run properly with the air filter removed because too much air is being sucked into the engine making it run too lean. Thanks For Watching!
Makes sense thanks for actually responding thumbs up!
Cameron Hud
Be sure to check out my video playlists. :-)
Ok
I’m going to try this tomorrow, my engine will start up but only because I’ve sprayed sea foam into the intake and will stall unless I keep spraying it periodically.. I’m wondering if this will fix it
It's the most common problem.
@@electronicsNmore yep it worked lol first pull it started and stalled, second pull she started up and kept running like a champ.. thanks for the video!
@@jordanb169 Great to hear! Be sure to check out my wide range of videos snd share. Thanks!
georgiaridgerunner79... I've replaced spark plug changed oil new air filter and cleaned ports on carb bowl.... still starts and dies... is it the ignition module...? 6.5 hp craftsman mower... probably 15- 20 yrs old
If you did exactly as shown in this video, and you still have a problem, then you may have too much air entering the carburetor, and not enough fuel. Try restricting some of the airflow by adding a small rag in front of the air filter. Last resort, try another carburetor.
Excessive oil wouldn't be a problem...?
John Mullins Anything is possible.
I've also noticed since changing the oil... It smokes a lil when it's started... But dies out whithin a minute or two of starting..
John Mullins
Check the compression.
Mine doesn’t have that bowl
Does concern me that so many people work on small engines without first removing the spark plug wire...
I only remove the plug wire if I need to work near the blade. The engine cannot start up unless the handle is pulled down and the crankshaft is rotated. Thanks for watching
What if you don't have a primer bulb like on my Toro
You still have a carb fuel bowl. :-)
I replaced the entire carburetor, removed cleaned the fly wheel and it still stalls after about five minutes of running. Then it will start for a few seconds and cut off. Also replaced the armature and it makes no difference. What is causing it to stall?
2 things. The first, and more likely, a faulty magneto(coil). When it heats up it can fail. The second, a crack in the intake manifold. When the engine is cold, the crack is tight, but when the engine becomes hot, the crack opens up allowing air to be sucked in. Thanks for watching!
If briggs & stratton could have made there engins from cow shite, I quite believe they would have. If you want a mower that lasts make sure the afore mentioned pair have nothing to do with it.
The bulb trick worked and kept my mower from stalling, but unfortunately I have already cleaned out that bolt holes... What else could it be?
josh maples I suggest you inspect those holes again. I never had one not work after cleaning them out. It is also possible that there are worn/cracked seals on the metering valve in the carb. Take the carb apart if pressing the button keeps it running. I'd bet those holes are still blocked.
Will do. Will report back with pics
I must be the only person who’s done this repair and still has a lawnmower that starts but won’t run! Is there a second most common problem to fix?
Make sure the hole in clear. Also inspect the carb diaphragm.
Air compressor to blow out and clean the air filter.
That works. :-) Be sure to check out my extensive video playlists for other great videos of interest to you, rate thumbs up, and share my channel with others. Thank you!
I went through these steps this morning and problem didn't go away. When I removed the "bowl" there is a gasket around the lip of the bowl that looks pretty worn but is still in place. Could that be the issue if it is worn enough and not creating a tight enough seal?
first of all ive been a small engine mechanic 14 years ...if your mower starts but stalls first you should blowout your air filter using compressed air if this doesnt remedy your problem then one should check the spark plug for fouling clean the plug and reinstall attempt to start engine if problem persists remove fuel tank clean fuel tank by partially filling with water slosh water around do this several times partially fill tank again with clean water look at water draining through hose if it looks slow one should blow backwards through fuel hose using compressed air (3lbs. max.)or one may blow with breath either will sufficiently clean the internal fuel screen now one should insert a shop rag into tank to dry up any residual droplets of water in the tank now one should reinstall tank and recinnect fuel hose and refill with fresh gas from a clean gas can if stalling persists remove air filter again followed by remaining air filter assembly then remove entire carburetor remove bowl using a small piece of wire (i use bread ties with the plastic burnt off) now insert wire into holes on the brass jet screw ensuring theyre clear now use same wire in all visible holes on carburetor now spray out jet screw then spray all holes in carburetor ( being very sure to hold carburetor at arms length and away from face) note sometimes one will need to replace the bowl gasket (with one shaped exactly the same as one being replaced) and also the primer gasket almost always gets damaged and must be replaced with one that is shaped exactly the same as the damaged one reinstall assembled carburetor followed by air filter housing and air filter attempt to start... if problem persists leave me a comment here for assistance.........
If you do see the this a reply would be much appreciated. I have done everything mentioned including a full carb/tank/lines removal and cleaning and still it runs for 1-2 seconds and dies. My mower doesnt have a primer and is auto choke. Im thinking it has to be something with the choke? Its a troybuilt 550 ex.
I just put on a new carb on my cub cadet pusher and still stalls.
Inspect the air filter. Does the mower run if you remove the air filter or try to restrict the air entering the filter?
@@electronicsNmore no. It still stalls.
@@petemycek9909 If you can keep it running by spraying WD-40(original type with propane in the can) or starting fluid into the carb air intake, then your carb is at fault.
@@electronicsNmore I tried the starting fluid but still stalls out.
@@petemycek9909 Compression, bad head gasket, faulty spark plug, or valve problem.
Did all this using Gumout. Injector is spotless, holes open. It still starts and stops a few times before running. Even changed the bowl gasket. Shucks.
Check carburetor diaphragm.
@@electronicsNmoreWill do. What's the carb. diaphragm/ look like? Thanks.
Look up your mower model online for more info.
@@electronicsNmore Heck. Must have been a fluke. She's starts and runs like it's new now. Thank you.
@@electronicsNmore Sorry. I got it. I just call it the gasket. I appreciate everyone's help on here. You folks save us backyard mechanics so much money. God Bless!
Can't find the carb lol
Has to be there! :-)
I did this and it still didn't work
Then you have other problems.
Check the compression. Replace the carb. because they clog up. Check the filter. The head gasket can leak. Tighten the bolts. The muffler may be clogged. The kill switch may be acting up. Check for good spark. Check for air leaks at the intake manifold.
Crappy outsourcing lawnmowers that are crap .
Do the w words GET ON WITH IT? Do anything?
What are you talking about?
You ramble
