Well, the stop switch theory is easy to test out….Simply disconnect the two stop switch leads from under the mag plate (be sure to tape off/isolate the engine end of the stop leads) and retest for shocks.
Your other ideas are surely a possibility as well. Using a coil tester probe is the only way to really check for high voltage coil or plug wire leaks. Loose connections or frayed primary leads could cause this also. I suppose a bad plug could create a problem as well….
The mag plate is not very well grounded on these engines, theoretically a great ground is not needed, the secondary voltage path is easily completed through the mag plate bushing/crankcase pilot boss. Nonetheless, it sure can’t hurt to add a ground lead to the mag plate to ensure a clean secondary voltage path.
