I have a 1940 A hand cranker. It always starts fairly easy, especially in cooler weather. Yesterday, I had it running in the yard, I left the area for a few minutes. When I returned it had stopped running and would not re-start. It seemed like it was getting fuel fine. I check both plugs and they looked OK. I then with a meter checked all wires for continuity and they were OK. I pulled the smaller, outside cap on the Wico Type C magneto. I checked both plug wire terminals with the tracking terminals on the inside of the cap. On the right (belt pulley) side, there was no continuity. I ordered a new cap and rotor. My question is: Wouldn't it continue to run on one cylinder? Will my fix be in by replacing the cap and rotor? Points look pretty good.
