Re: no spark 9.9 force
With the plug wire attached to the plug (plug in motor) have somebody pull the rope and you watch for any sparks or flashes coming from the wire or anywhere else for that matter. Do this in the dark so you can see the spark. If it starts shut it off asap.
If you don't see anything unusual go buy a $4.00 spark tester at Harbor freight and verify your not getting spark at the plug.
I don't think a bad coil or ground is going to cause you to get shocked by holding the wire. Sounds like you have good spark but the spark is jumping from the wire to a ground (your hand being the ground).
