One thing that you need to remember is that you will need resistor type plugs. This will prevent unusual things from happening. The Onan 3600 LP generator has a section on this. So I assume that the same would be true for the other spark fired generators.

I don't have your manual, and I hope you do. If not, a call to your friendly neighborhood Onan dealer should get you the info. This much I CAN tell - After years of experimenting, I have found that Autolite plugs last a whole lot longer than any other I've ever used. I have measured gaps after a year of racing and the gap was almost totally unchanged. Suggest you give them a try.
