I bought a 30KW generator with a 3.0L GM engine on ebay. (no returns). Been running an aircooled on natural gas. I discovered that the gas company can not provide me with sufficient volume for the new one. I live in a small town and the gas company runs 4oz pressure in the whole town and I am on a 2 inch main with other customers.This is a new unit, never been run but surplus. After I learned that the gas company can't provide sufficient gas, I set out to convert it to LP (vapor)I was told that the spark needed to be retarded 6deg. I then discovered that the engine was dressed up in an EPA costume and that the timing was controlled by the ECM. I contacted the Engine outfitters ( I don't know the official designation) I was told that I would have to bring the engine in (to Oklahoma) and they would have to change the wiring harness and regulators as well as adding a vaporizer. I told them I didn;t need a vaporizer that I would be running it off vapor from the tank. They said the only certification that they had was for Liquid LP and they would have to build it to certification. I hooked it up on LP runs great, didn't set any codes on the Micky Mouse ECM. but I was told that it would possibly damage the engine if I didn't change the timing. I wasn't able to check under load . Any suggestions would be appreciated.
