Onan 4000 Generator Problem
Hey all, I recently posted that the Onan 4000 on my Fleetwood was roaming and would only stay running if I wedged the Governor open, but that is not the case. I went out today to check the adjustmen...

Has anyone ever pulled one of these carbs off with the generator still mounted in the coach, or should I go ahead and put a jack under it and drop it down.
If there's any chance of doing it without dropping the generator, attempt that. It's no fun to drop the generator--not particularly complicated, but a good bit of labor.
To drop it, one generally needs to disconnect the fuel line, the positive and ground DC connections, the remote start controls, and the AC connections, assuming the wires/hoses are not sufficiently long to reach the ground. If the fuel inlet for the generator is lower than the fuel tank, which is not at all uncommon, you would be well advised to get the fuel level in the tank below a quarter tank or so to avoid the possibility of siphoning it all onto the ground.
Disconnecting the AC lead, at least in my case, involves removing the voltage regulator/control modules (and hence also starter solenoid) from the generator to get to the ground and neutral connections, and also removing or at least partly removing the little control panel to get to the generator circuit breaker for the hot lead.
If you do end up dropping it, make some measurements first and if needed drive that side/end of your motorhome up on ramps so you have enough space under the skirting to get it out from underneath. A bit of planning ahead here will save a lot of aggravation. The generator weighs something like 175 pounds or so.
Don't ask me how I know this...and, on completely unrelated topic, be glad the starter motor doesn't need attention.
