Sometimes it won't start and if it does it dies right away or I have to give it gas and then it stalls out. If it's running its bogging down .kinda sound like it wants to stall but doesnt till it stops at a red light. Sorry I'm just frustrated. I have to give it gas while trying to start it. Most of the time if i don't keep a small.amount of throttle it dies on me. Same thing at a red light I have to constantly start it after it stalls out or sputters out and give it gas.. I tapped on the top of the carb and it sputtered out.. But then ran fine for a little while. The mechanic said that the FLAP. INSIDE the carb was worn out? Is he blowing smoke or is this true? Thks guys
