I do not know how much I helped them. It took a week for us to fix everything. They were on their way to Texas and ended up returning to Chicago instead because I delayed them so long.

I just went through fixing my Onan problem.
It wold start and only run a few seconds.
Looked like a fuel problem. If i jumped the fuel pump for a few minutes it would start again.
I bought a new facet FEP60SV with a new filter and nothing changed.
Next I removed the carburetor when I took it apart and cleaned there was a small piece of smegma, on top of the nettle valve seat, blocking (slowing) the fuel from entering the float bowl.

Well I now have a new pump and filter and some more experience.
Hope all have fun with there problem Onan.

I’ve fixed a few with that exact problem; I expect that it is a piece of the seat material that has been attacked by alcohol and behaves sort of like a flapper valve to block the fuel coming in from the pump. The usual giveaway is the completely dry carb bowl that you find after the engine dies.

Yea I don't know where the smeg came from but it did look like rubber. May have come from the 40 year old hose.

Ran real good till I changed the rubber mounts. made me think I disturbed something.

Running better than ever now.
