The original problem was that 8N wouldn't restart. So we went down the path that the EI current was too weak. Then learned that the coil was grounded to the engine and not the resister. Some assumed that the coil was fried because of getting the full 6 volts and not the voltage coming through the resistor.
So I got a new coil and ran new wiring from the resistor to the coil. When I did that, 8N wouldn't start at all.
Went back to the old coil and grounded to the front of the engine which is the way it was originally. It started but not a restart which to this day I do not understand.
I then discovered the plugs were gapped wrong and the spark plug wires were screwed up under the rubber which insulates/protects the plugs.
Once I put in new plugs properly gapped and fixed the plug wires, all problems went away.
I now have a new coil with a new grounding wire from resistor to coil. All is perfect.
1 - don't assume that the coil is bad if the 8N won't restart
2 - don't assume EI on a 6 volt is bad if not restarting. Glad I didn't go to the effort to pull EI and install points and condensor
3 - I needed a way to test the spark which I didn't have. I have since purchased a spark testor which will arrive tomorrow.
