  • Not only an excellent tutorial, but also a powerful confidence builder to attempt the repair for the neophyte! Thank you very much Jeff!

    Rebuilt my craftsman push mower today after watching your videos. Thank you for making it so easy to follow , and again great camera work for us novices. Have some smoke coming from exhaust area but nothing looks amiss. Mower runs at correct idle now and most importantly cuts the grass!! Just in time for my kids to help out during quarantine. Thanks again Jeff!!

    The assembly of the lawn mower could be done without any problems youtube.com/post/UgkxTPN04aT-Qdjr_KS3ql7ng8wnU3wws… also recommend I just puzzled something about the red strange “key”. However, it quickly turned out that this creates a kind of contact bridge between battery packs and lawn mowers. An additional backup as a father of a 1 year old nephew is great!! :-)

    Dear Jeff, As I am a small engine Mechanic you illustrate this step by step Carb rebuild like a pro!, I'm very impressed.
  • @crotchcricketts
    Great video, very informative. I especially love that you're listening to Tool in the background
  • Thank you for the WD-40 tip for the seat! Made all the difference in getting the float to sit properly.
  • @badger7015
    unquestionably, the best home repair video i've ever seen. thank you!!!!!
  • Today I cleaned all around the Governor Spring and replaced the dirty air filter. Idled way too fast then died. Will try to rebuild the carburetor. Thank you for your most comprehensive video!
  • Great video. I just did this very job today 2/23/23. I wish I'd watched this video first!
  • @samanth7777
    I did it, I did it I brought my mower back to life.. Thank you thank you Jeff.
  • @w0lff1e
    Great video! I didn't do a rebuild but a replace. Everything was super clear from the video and well explained. Once I had everything put back together the engine started right up!
  • @tlalmt
    OMG I DID IT MYSELF!!!! Thank you sooo much for the slow concise step by step instructions, with great tips.   although I DID NOT use coke to clean, used gum out carb/choke and parts cleaner...Briggs & Stratton Quantum 725.. just mowed the lawn no problems. YIPPPPPEEEE!!!! Namaste'
  • @supertroupin
    Thank you so much. I rebuilt two of these carbs yesterday; both mowers started right up. The guys at El Mel in St. Charles also told me to only use premium gas to keep the engine cooler.
  • @fzee532
    Thanks for the detailed instructions, I rebuilt the carb and cleaned all linkages, the beast now starts on first pull!
  • @scottlowe514
    Really helped had cleaned everything like you said but after reassembly engine started but would not run. Took off the bowl and cleaned the main jet and found some debris in the bowl cleaned and reassembled, ran like a champ after that. Thanks for the great video
  • @sygerrryc
    Loved the "tech tip of the day" didn't know about that trick.
  • @awongutume
    Well illustrated and narrated. Thank you for taking the time for this very edifying carb rebuild.
  • @joeboxer3365
    Jeff thank you for the video, I repair mowers, more on the quick, cleaning out gas tanks and then carb cleaner and compressed air for the passages. The one thing I do different is rather than using wire I find torch tip cleaners with various sizes clear out the most stubborn deposits much easier. Also at same time I use the tips to clear the 3 passages and check flow to the bowl with carb cleaner to make sure the priming system should operate properly.
