DOHH??? What is that? DUH spells DUH; DUH!
DOH a female deer?

My propane Onan is notorious for not starting after sitting. We have mud wasps that love the smell of propane and they go up a black rubber vent house and deposit mud and clog it. I have to then use a coat hanger to snake out the crud and clear the line and it fires right up till the next time. To fight this I put a golf tee in the line which works great till the next time you go to use it and it won't start cause the line is plugged with a golf tee. DOHHHH, made me laugh. But easier to fix.

Thanks Everyone. Will definitely look into the suggestions.

What fuel does it use? If it is LP, you need to check those tanks as well.

In addition, my generator has a couple of fuses on the front. I had one blow and it would not start either.

My Onan needed a fuel pump, circuit board, and a carb rebuild. I did the work myself and now it runs great. The difference is mine hadn't been started since 2000.

I must have started in december. i think

How long has it been since you last started it?

You need at least 1/4 tank of fuel for the generator to operate. That's assumining the generator is fed from the chassis tank. Have you replaced the gen fuel filter lately?
The filter may be attached to the bottom of the carburetor.

Let us know if a low fuel level caused the problem.

I definitely Check the tank in the morning. Thank you
