Finally got around to looking at the 8N today. Since the spark plugs were old, I changed them. It runs better, not good, but a lot better.
Dell, I also looked at the switch. It is not the factor two-wire switch. It has several terminals on it with wires coming from them. This must have been done when my father had the 12-volt conversion done in the early 1990s.
Thanks for all your help. I will keep pursing this. However, I will most probably have to get someone to repair it since I am not knowledgeable about engines, etc.
