2000 Duece, stock cv carb. The fuel is being pulled through the main jet at idle, fouling the plugs. Took the carb apart, cleaned all the passages with carb cleaner and compressed air, set the float according to the manual, replaced the o rings, all the things you're supposed to do. The kit had the wrong float valve, so I used the old one but it looked ok. I have another bike here with the same carb and no fuel passes through the main jet at idle. Any advise would be welcome!
