ok so I have 2 old badger 80's. 1 runs like a champ (after new valves, seats and rings). the other was running great until it up and died. No spark. I have swapped parts back and forth and I know it isn't the Key switch, CDI, spark coil, run/stop switch, or spark plug. It turns over just fine, the neutral switch is functional (cuts off in gear and turns over in neutral). There is not one single spark coming out of it. I don't know what to do next. Should I dig into the stator, magneto or what? Please help
