@charliebrown39 couple more things for you to check:
Check the air gap between the flywheel magnets and the laminations of an externally mounted coil or module.
Check the flywheel magnets for the proper strength using this rough test. Hold a screwdriver at the extreme end of the handle with the blade down, move the blade to within 3/4 inch (19.05 mm) of the magnets. If the screwdriver blade is attracted to the magnets, the magnetic strength is satisfactory.
Examine the stator components.
Check the ignition cam for roughness.
Check the movable point arm that rests on the ignition cam for wear.
Check the spring steel on the point assembly for evidence of excessive heat.
Check contact points for wear. If they are pitted or burned, this is an indication that the condenser is not functioning properly. If any of the above are faulty, replace accordingly.
After the points are replaced and engine is retimed, be sure to clean the points with lint free paper. An engine will not run smoothly if the points are improperly set or coated with even a small quantity of oil, etc.
Examine the coil and lamination assembly (either internal or external) for cracks in the insulation or other damage which would cause shorts or leakage of current. Make sure the electrical leads are intact, especially where they enter the coil.
