Well that's what I was hoping to find. I looked and bent the plug wire all around and couldn't see a crack in the insulation. I put one wrap of electrical tape around it just to play devils advocate. I also replaced the kill switch wire. Because it's so cramped in there I ended up soldering the coil end of the wire to the blade, because no matter how I placed it, the terminal looked like it would hit the caseI have had all kinds of issues with Mini Macs but never been zapped! It's such a basic ignition system, I bet when he tears it down he'll find a spot on the primary coil wire that rubbed through and is touching the chassis.
The bizarre thing is that it doesn't misfire, any time I've been dumb enough to introduce my body into the ignition system of a simple engine, I instantly start to do the jitterbug, and the engine stops firing!
Put it all back together and still have the sparkling and shocking problem.
I didn't pull the flywheel to inspect the points like I probably should have, but I just didnt think they could be the culprit. Guess I'll take it apart again.
The whole no misfiring thing has me puzzled as well. Gotta be something stupid. Wish used parts were easier to find for these things around here, but if an older saw is running around here the owners think they have some rare saw and want more money then I'd pay.
