1990 Winnebago Warrior Kohler generator

Might have a low oil level, or low oil pressure switch.

Change the oil/filter and the fuel and air filters. Take care of the basics before you start troubleshooting. These are routine maintenance items that should be done on a regular basis.

Possibly it is a low oil situation or a bad sensor.
Is it pumping fuel to the carburetor?
Maybe your rubber fuel lines are collapsed.
Are you getting a spark at the spark plugs?

Perhaps a silly question, but is your gas tank low? Motorhomes are often set up so that the generator fuel intake is at approximately the 1/4 full height in the gas tank so that you can't strand yourself by running completely out of gas running the generator. It's not always a precise level.

It's also possible that the fuel pickup tube in the tank fell off or developed a hole and you aren't getting gas for that reason. It also would not hurt to check the fuel pump for the generator (it presumably has one) and typical small engine repair things.

I'll check the oil. I wouldn't know where the pressure switch is.

Thanks

I would be willing to bet that there is a manual on-line that you can download. Then you can catch up on the maintenance. I don't even know what model and spec it is or I might just venture an opinion where to start.

Thanks all,
I'm looking for a manual now. The oil is low and I only have 1/8 tank of gas! I'll fill the oil once I get the manual. I want to replace the plug, no problem there. Accessing the filters looks like a pain so far.
So I do need a good maintenance session as I've written, this RV sat for 2 years unused, unopened in Houston. The plastics are cracked and breaking but I can repair those. I've already repaired the fridge and furnace (twice). Now the water pump isn't pumping though I did pump it dry for the season and left all the faucets open. Would that make some sensor not start the pump?
Thanks again. It's a learning curve!

it's a Kohler 2.5 25CZ

Found the manual so I should be good to do the maintenance and then fuel and oil up and I'll bet she works!

I'm almost willing to bet money that the 1/8 tank of gas is the whole problem you're having. Obviously it's a good idea to have the oil at the proper level, as is doing whatever other maintenance is reasonably needed.

I'm sure that's it-I hope. But it seems the most reasonable

Thanks
