I have a 66 cc motor and the carbs poors gas out of the air breather part when it runs and it's not running right at all but when i had my buddys speed carb on her she would fly man,, so what the heck is my problem with my carb??????????? Also when it warms up and when you pull the clutch in it will high rev like a mother until you kill the motor also.weird right? need help with that also.it almost looks like the gas is being blown out of the carb when running.
