  1. There is one thing you left out, you know, where you clamp the hose off close to the fuel tank so you can cut the line and install a shut-off valve. Closing the fuel shut-off and letting the engine run until the carburetor is dry does help prevent the ethanol caused problems. Just a thought…

  2. thank you for this video. I bought a rebuild kit with the Sears / B&S part number and it was correct but the video that Sears had for the process, using my tractor number, was for a different carburetor, no plastic float base, it was integral with the carb base. Fortunately, I saw the cameo for your video showing the plastic (nylon, maybe) float base and the rest is history. thanks again.
