So I get to the ramp this afternoon and the motor won't start...so after I get it home and tear it down I have come to the conclusion that the coil on one cylinder is not getting power. I changed out the coils, plugs, and wires and I could get a spark on everything except when I used a single wire coming off of the power pack. Have I missed anything or do I need to go ahead and order a new power pack? Thanks
