Sounds like a bad coil. Pull the one off the other engine and try it.

I have tried swapping the coil & what l would call an ignition module with no help
the only difference i found with my test light was no power on the white/red wire going into the distributor on the no start motor
Any ideas?

This sound stupid but it's happened to me. Did you check the dead man switch?

Dead mans switch checked out OK
I'm thinking maybe Pickup module in distributor?

Good News,
Replaced the Ignition sensor last night and she's running like a charm again
Now I just have to wait for the lake to thaw
Thanks for the Help
