i dont have one of the gauges. its a brand new piston so its not all scratched up or nothing and my cylinder is very clean. ok i just sprayed starting fluid on the spark plug and it started right up but it will only stay alive if i give it gas, once i get off the gas it dies. i tryed changing the timing and that didnt work so i put it back where it was, iv tryed changing the idle screw a few times, wasent helping. i guess im just not getting enough gas to the piston.the bowl on the carb is filling up so its gotta be something between the bowl and the intake. my jet it cleaned so i really dont know what could be wrong.
