It's a 1975 Mobylette Duamatic, which I've had just about enough of. Ron, I've tried to use your "It's only an engine, it's only an engine..." but I still get so incredibly frustrated wasting the entire day and getting no further. I've even tried "serenity now, serenity now..." but still I get nowhere. I took apart the carb, used carb cleaner and blew out everything in sight. The float seemed a little different then you described Fred, it was about the size of a quarter (I hope Canadian quarters are the same size), about an inch thick and had a needle passing vertically through it with more sticking out on one side than the other. I took the float out, cleaned all around where it sits etc. Still when I turn the gas on, gas comes pouring out of the main jet. I remember a while ago the main jet had this kinda hard stuff on it, which makes me think that someone tried to fix this by just putting something over it, but I don't see how that could've worked. Maybe I'm missing something really obvious, at least I hope so...
