Pissed off with motor, want to change

Anything that causes unburnt fuel in the exh can cause popping. So yeah, the carb could be the culprit. It's just the lessor of possible causes and the cheapest way to eliminate the more immediate possibilities is to diagnose the electrical. IMO, the ignition voltage to the coil is low and there's a lot of voltage drop. But like Wild said, it's possible that is just a normal situation. That's why I say test the ballast legs, or just jump them to get as much voltage as you can to the coil and see if the pop disappears. If it doesnt, it's more than likely the carb. If it does, it's the ignition wiring. I just don;t like buying stuff to diagnose. Free info is always the best....lol
