My Onan generator 4000...

No battery. This is a power generator providing electrical power to my motorhome.

Mechanic's Assistant: What year is your 4000?

1998

Mechanic's Assistant: Are you fixing your 4000 yourself? What have you tried so far?

225 hours of operation.

Mechanic's Assistant: Anything else you want the mechanic to know before I connect you?

Changed air filter, removed carburetor and cleaned orifices and changed plugs twice. I also inspected the governor rods for any bends and there are none.

Apologize for not responding sooner, but I'm boondock camping in Mexico and have no internet connection and intermittent cell phone service. Thanks for getting back to me. I have checked the fuel lines and filter, all ok. I closed the breaker for out going AC and after that I tried starting and it ran surging all the time before shutting itself off after a few minutes.
