Got a guy wanting to trade me a ATC70 for my little dumb and dumber mini bike. Payed $400 for the mini bike, only reason i want to get rid of it is I can't ride it in the city. Been stopped by the police twice already. So for now it's just sitting and i need to rid myself of it. I think a 70 is a fair trade. 70 looks perfect but is getting a weak spark at the boot and no spark through the plug. Points, condenser or coil? Any ideas or suggestions.
