I just spent about an hour performing this task described in the video, and this dude was exactly right about the whole breakdown and re-assembly. Excellent description - I never would have been able to do this without this video.

Thanks, man!

[nutbag]

Can't thank you cleaning my carb for first time and the jet fell out.I didn't know where it I watched your like a scalded dog now.Big thumbs up!!

[aldoperales]

So I had this problem with my John Deere D140 riding mower as well. It has 189 hours of operation. I took the carburetor off and and took it apart. O rings looked good and no dirt. Gaskets were clean. I put everything back in place. Long story short, it need up being a dirty fuel pump and a clogged fuel supply hose. I shot compressed air into the line and I heard a BANG. It was the dirt that shot out of the fuel supply hose. Installed everything back and mower runs like new. $25 fix.

[kellysousley]

THANKS! Yep, jets were in the bottom of the fuel bowl. Ordered kit you recommended. Just mowed the lawn! Never lost one rpm even in the thick areas of lawn.👍👍

[larrycook]

Thank you so much for this video and from reading the comments below someone had mentioned the low cost of a complete carb. So that's what I did was to just get a new carb. I did disassemble my old one and sure enough the jets fell out of it! Seems the new carbs don't have jets in them anymore. Thanks again for your information though and my problem seems to be cured!

[fleamine]

I love the background music and the way you illustrated this video, im 50% deaf, I could hear you just fine.

[johnclarke]

A very good video, John. I thin those O rings were messed up by the ethanol you used in your FUEL. I use nothing but premium non-ethanol fuel in all my outdoor power equipment. Four cycle gas gets one ounce of B&S AFT fuel treatment and one ounce of MMO per gallon of gas. I get my premium non-ethanol gas for $3 a gallon, locally. A little more costly than regular ethanol gas, but it eliminates "most" gas issue problems we find in two and 4 cycle engines these days due to the ethanol.

Great video! I have the exact same carburetor but the emulsion tube shroud is black and does not have the two jets you showed, the engine ran fine until recently and surges and runs only with the choke out. I thoroughly cleaned the carburetor and replaced all the Orings. Do you know if any of these Nikki carbs have version’s with no jets? What do you think is going on? Thanks much!!!

[hgj]

Just did this on one of my mowers. I also cleaned the light rust off the flywheel magnet and coil faces to improve spark.

[rb.]

My sons would start and run about 3 seconds and die. We pulled the fuel line off at the carb and made sure it had fuel getting to the carb. It did. So I pulled the fan guard and shroud bolts loose, you do not have to completely remove the bolts, only back them out. Then I removed the intake manifold and carb bowl. I cleaned the carb out and blew out the jets and reassembled the engine. She starts and runs like new

[robertbunnell]

when installing those jets the best thing to use is a tapered toothpick!! you can push in the jet & it will hold the jet !! jets are very soft you may actually do damage to them using those metal pick tools, plus they slide ooff the pick tool.

[richc]

Great video, exactly the problem I'm having. Thank you for taking the time to help me out, very much appreciated.

[jwk]

Very informative, can't wait to tear into my 24HP B&S V-Twin that has never run 100% from new! Thanks for the parts link.

[ttrackspeed]

Really helpful video.My simplicity riding mower is about 10 years old and I have been fortunate that this is the first time I have had to tackle an issue with this mower and the Briggs & Stratton engine.Need to ask and confirm before I go further with the carb, Is my mower issue solution the same carb fix as described in the video for a surging engine repair?The video speaks to a surging engine and erratic engine performance.  My engine issue is likely related to the carb too, my mower specifically runs with the choke closed for several minutes and then eventually floods out and quits.  When loading up the engine under power, the engine quits.I've replaced the plugs, the air filter, fuel filter, and sprayed the carb with sea foam. I still need to replace the fuel pump.  What do you recommend my next steps to take? Am I rebuilding and cleaning the carb jets or do I have a different issue to tackle and path to a solution?Any additional insight and help would be great.  Thanks.

I got a john deere z355e v-twin 22hp Briggs and Stratton motor and I cleaned carb and check spark both are good but when I start my lawn mower it runs good but once I start to turn blades on and mow for 5 min then it starts to die. Might be fuel pump but I'm not sure it only has 59 hours..

[ryanbuckner]

I appreciate it Ron White! Glad to know you have something to fall back on if blue collar comedy doesn’t work out!

[PageMarker]

Excellent video even if it is 7 years old now. Grateful for the sizes of the screws that need taking off. Major surprise seeing that o-ring so bloated out. They don't make Buna like they used to!

[PrepperMountainSolutions]

Nice, you saved my butt! Just ordered that kit from your links in description, Cheaper than Briggs by $30!

[ronaldlicari]

OK first I would like to say this is one of the best detailed videos on this I've seen. With that said I have a problem. The O ring you said that comes with the kit is the wrong size, its for another carburetor piece that's metal and it goes on the inside of the other piece. I tryed to put that one seal that came with the kit on and there is noway to do it its 14.5mm, I had to order the correct one from a small engine shop that fit perfect. Anyway other then that good video.
