I'm really impressed that you found this. I'm very glad you shared it.
You lost me at trigger . It is an awesome thing have smart fellers like you guys around though.

With the poor grounding issue, did you ever hold the sparkplug near the cylinder and verify spark? If so, would it shock you? I have tried this and got shocked, but haven't found any damaged wiring. I have never been shocked before checking the spark plug like this.

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.
