I watched some other videos before I cleaned my carb and this one after. I wish I had watched this one first because it's the best by far!

Thanks for uploading this. I was unfamiliar with how these Carbs worked. My mower had been running poorly and finally got to the point where it would only run from the primer bulb and shut off. I put my Carb and Tank a bucket of warm soapy water while I went to pick up the new Diaphragm and Gasket $4.10. Once I got back I dried everything off and reassembled it. Fired right up and runs like a new mower. You got me up and running in no time. A big Thank You from Pennsylvania! 👍

One of the most profusely explained instructions on cleaning and adjusting B&S small engine plastic carbs. Thanks for sharing.

[Pete.Ty]

I believe this to be the best instructional video on the refurbishment of a B&S carburettor that I have watched to date. It’s a clear and concise step by step guide for someone with only basic workshop tools and knowledge.

Got a 'broken' lawn mower from my dad. Hadn't run in 10 years. Quick trip to Lowes for some parts and I'm up and running! Had to spray some starter fluid in the carb to get it to start. Thanks for the clear and stellar video!

I've watched a number of these in anticipation of cleaning my scarifier carburetor. This has been the best and most confidence building by some way. Thank you

This helped me out a tremendous amount. After the diaphragm replacement it fixed my mower.

Thanks for the great tutorial. I use Torch Cleaner files to probe Main Jet. I used a small flat blade screwdriver to pop out the plastic Main jet/emulsion tube which has 3 small holes in its length. Mine was black and is secured by a tiny O ring. There is a flat spot on the top to pry it out. Work carefully! Mine is the 5 bolt model.
Be sure to seat it flush on reassembly. Carefully using a fine flat file I filed the bolt hole bosses adjacent to the block where the carb base was warped. This reduced the gap somewhat. I used some Permatex Aircraft sealant along the joint between those bolt holes.
I used a straight edge to see the warpage left between the 2 holes. That leak area sometimes accounts for the oily mess on the carb and block in that area I was told. Mine had the Diaphragm on the Carb side instead of the Tank side.
Seems right, but I reassembled with the diaphragm on the Tank side, then the gasket. Edited.

Literally only 15 minutes of work and my Briggs & Stratton pressure washer started up again and ran just fine. You even addressed my minor oil leak I found. Great video my Guy

[shaheb]

Big appreciation mate. I'm a beginner and I found this video the best., , every thing in perfect details and easy to understand

[waynestefinashen]

Easiest carburetor for anyone to clean just need to be sure you change the gasket and diaphragm to ensure no issues like air leakage. Nice tutorial.

[shortliner]

I believe you addressed the problem I'm having with my B&S mower. It tries to start after pushing the primer bulb but then quickly quits. I'll make sure that port you showed is good and clean. Great cleaning tips!

[heatherwolfe]

I've paid for someone to "fix" my carburetor several times. They never took it apart like this (I always watch to try and learn) but did something to unclog it. I kept having problems so decided to do it myself. Thanks to this video I discovered I was missing a gasket. I disassembled the carburetor and cleaned it myself and will do all my own small engine work from now on. Next up, oil change LOL

[elieli]

Seen several videos on this subject and this is THE Best video hands down....

[kuruption]

Fantastic video! Very thorough. Mine wasn't starting, so I went through the whole process. Took out the carb and tank, cleaned it all with carb cleaner before taking it apart. Took it apart, cleaned everything thoroughly. Washed inside the tank, then re-assembled, fresh fuel! First start and it started. Smoked a bit, so I checked the oil; oil was low, refilled the oil and restarted. Smoke is gone and engine runs like a champ. Thank you!

[philliphall]

To point and no story telling
Great way to teach and not waste time

[briangilliland]

I thought I had it but your video took me places I haven't been. Brilliantly clear and concise
(Hopefully it has saved me buying a new mower)

[wcb]

Great video, since I have one just like it. My problem was a missing governor spring!! Thanks for including the spring description and PN in the memo section for this video!! I couldn't find it on my own; doing my own searching.

[ken-fozu]

Best how to video on this carburetor cleaning I have seen yet.

[roberts]

Very concise and detailed video. I have this same engine and carb. Learned some things I should be doing whenever I remove and clean my carb.
