Carb is clean that's for sure. Float looks good too? Not sure how I'd set it or if i can... also the boot that connects the carb to the engine is not perfectly tight on the carb. The clamp doesn't tighten very much for some reason so I can still move the carb around in the boot with it tightened all the way. Anyways I ordered a new oem clamp so I'll replace it. Could that be the problem? I sprayed carb cleaner all over it while running and didn't make a difference so I wouldn't think it has an air leak there?
