Lets See If You Guys Can Figure It Out

Wow! In a million years I would have never guessed that based on the symptoms. But now that you've nailed it, it sort of makes sense. Without any ground the trigger wouldn't work at all, but with an AC ground through the regulator and an output impedance of 150 ohms through the trigger coil, the trigger would occur but would be delayed.
I'm really impressed that you found this. I'm very glad you shared it.

You don't hold the spark plug "near" the cylinder head. You must have it connected/pushed/jammed up against the cylinder head. The spark is trying to return to ground. If the threads of the spark plug are away from engine ground, and you are holding on to it, it will try to get to ground through you. Yeah, you will get shocked. At the spark plug end of things it is really low current. It stings, but isn't dangerous (unless it makes you jump and insert yourself into something dangerous). I'm more careful with the primary side where the voltage can be 300 volts (at speed) and has substantial (and dangerous) current available.
