QUESTION: it worked for the first couple times now it doesnt,it will start and stall,start and stall,sometimes just about kills the battery,let it sit awile go hit the start button without choking it and it fires right up,i cant figure it out,thanks,randy

Answer
Either the choke circuit is plugged or you are over choking the bike. If the choke circuit is plugged then you are going to have to rebuild the carb. If its just over choking then once you start the bike you should push the choke in as far as you can, but the bike still runs. If you keep the choke out to long you flood the motor and foul the plugs. If you dont need the choke to start the bike dont use it
Good luck and happy riding
