my buddy has a yamaha blaster. we rebuilt the carb on it and now it is getting to much gas. everyone is telling me it is all in the float but we put a new one in and that didn't help it. It is getting way to much gas. when you turn the gas on and key on it is pouring gas out the overflows without even running. when you do start it up it will run but has no power at all until you shut the gas off and it revs up right before dying. we have done everything we know to do besides taking it somewhere. does anyone have any help or suggestions?
