There is a kill wire that should be hooked up to the throttle, near the end of the throttle linkage. If that was loose and dangling, perhaps touching the frame, I could imagine a sudden shock. If the plug wire is cut, pinched under the shroud that would short out the plug. The condenser wire under the flywheel could also have been rubbed bare somewhere along their length, especially under the aluminum cap that covers the points and condenser.

Yes, the coil must be properly gaped. A business card is often used but a feeler gauge is more accurate. But, if the engine is missing (possible ignition problem) and you are getting shocked (ignition system related) you should also suspect a bad wire. Have you checked the stuff that XSleeper listed?

If the engine only runs with the choke closed then something in the carburetor is clogged/plugged. A good cleaning if often all it needs.
