Reply To: 1940 champion 3.2 hp coil

Have you checked the condenser on this? Those coils are usually good. There are several other brands that use that same coil. Also check the points with your meter to make sure the resistance is near zero. I have had problems with connectors having high resistance so that is another place to check.
Spark plug is a #7 or a Champion D16 gapped at 0.030″, points gapped at 0.015″, oil ratio is 3/4 pint oil to a gallon gas.
Good luck with your motor, they do run well.
