Onan Generator Hunts Under Load
Hey folks! I wanted to first offer my thanks for those of you who answered my previous post. For those of you who don't know the backstory, I bought my first motorhome (2002 Fleetwood Tioga 24d) last ...

Thank you for all of your replies -- the wind died down so I went outside and disconnected the main fuel tank to run it with the external can (with the Seafoam still in it). I let it run for a few minutes and then tried the A/C. It immediately started hunting again, so I think we can rule out stale gas in the main tank.
So while the AC was running and the generator was hunting, I tried turning the sensitivity down... literally all the way until the screw wouldn't turn anymore. The good news is that the hunting slowed... to the point where the A/C didn't panic and shut down. The bad news is that it still hunts... and now it seems to hunt on no-load start-up.
As I said, I am not very mechanically inclined, so trying to read the service manual to adjust the governor doesn't seem to help me figure it out. As I understand it, there are two screws that I need to worry about -- the speed adjustment screw (to dial in a no-load voltage within tolerance) and then the sensitivity screw on the governor arm (to dial in the correct frequency/voltage with a load on it). Maybe someone on here can explain it better than I can understand it through the manuals? Or maybe someone knows of a video on how to adjust these properly? I have scoured the internet and can't find a tutorial on how to adjust these correctly.
Thanks for your help! :)
