  1. Of course the repair video was stellar and your instructions worked like a charm. However, I found the greatest value in your existential comments at the end of your presentation. With a little introspection, aided by some incense and candles, (SAFTEY NOTE: Keep the incense far, FAR away from the dad gum gasoline!! Ouch!) I found that it no longer even necessary to murder the innocent blades of grass. Thanks to you, I am now free from the vicious cycle of committing weekly 'lawnocide'! (Side Note: Could you maybe put together some teaching about the zen of dealing with 'Chiggers'?!?!) ; – )

  2. NOT NECCESSARY to undoe carb……JUST KEEP SPRAYING AEROSOL THEN BLOCK INTAKE WITH HAND……old fuel will suck through……ALWAYS USE FILTER FUNNEL not straight from can.

  3. Thanks man! You just saved me having to pay some other guy to fix it or buying a new one. I'm lazy, just not $75 to have someone else do it "lazy"

  4. Briggs & Stratton systems are pieces of crap. One year in and no start, no matter what. That would be a good slogan for this joke of a company…

  5. I just did this on this exact mower, got it running again smoothly to cut a big patch of grass. However, it then choked out again and won't stay running now. Any ideas folks?

  6. Ben, thank you for making this video! You're DIY video helped me to fix my mower & finish my lawn. Your explanation of leaving gas in your mower made me realize why I was having starting problems. Thanks again! 😉👍
