I just bought a couple of dual fuel conversion kits for 2 different generators, one is a Yamaha engine, and the other is a Onan. The kit alows you to run propane or gasoline. It is connected between the air intake and filter.
My question, if you are running propane, do you need to turn off the gasoline valve? There is no mention of it in the instructions.
Damn buying stuff off of E-bay, no techs to ask!
