The air vent 1" tube is leaking gas when the scooter runs. The gas and vacuum lines are hooked up correctly. Could it be an issue with the float sticking?
could be, if i were u id take out the carb, buy a couple cans of carb cleaner, and new gaskets and clean the hell out of it... im thinkin its the gaskets tho... make sure the lines are GOOD, not ok, and make sure they are tight
