No clue. I didn't see any signs of heat. Wires all seem tight. But one of the bolts to hold powerpack in place was not tight. Are you saying it's not normal for power pack to go bad?
I switched the two wire from power pack to coil and then I had spark on opposite plug. The motor wouldn't run on bottom cylinder. If I switch them back it will run on just top cylinder. So is that meaning the power pack is the problem?
