Your going to have to take the carb off and clean it, or possibly replace it. With old gas in it turning to varnish you might never get it out.

Bought several parts for my 4k Onan generator. Oil cut off switch was bad.
Have found a couple wires with wires exposed. NEED HELP on part location.
I removed points and all I ended up with in my hand was the point plunger rod.
Realized something has to be there as plunger rod is less than half the size of Port on engine and access hole on point base. Called my Cummings dealer and he said he does not show any other part. He said a new plunger rod might seat better. I am not a professional mechanic but I know I somehow let a seal or something get away. Have used air hose on engine hoping to force part out, no luck.
HOW TO HELP....My generator is a 1986 BGE model . If anyone has a part number for the guide or seal that holds that plunger rod stable, please let me know. I have searched and searched. Thanks, Jerry

Try this site: https://parts.cummins.com/?_ga=2.186...gsn-entry/main
Enter your serial number and parts specific to your generator will be available.

If that doesn't work, go to this site and ask them to send you a Service Manual! https://www.smokstak.com/forum/

In the 4+ years I've owned mine (Micro4K) prior to filling the fuel tank for storage I dump in a big bottle (treats 80gls) of Sta-bil fuel stabilizer then fill the RV tank full 60 gallons. Then I fire up the generator and let it run ~ 30 mins or with a load.

Shut off. And store RV for ~7-8 months.

Pull RV out check everything over. Fire the generator up. Bingo we have lift off

One other thing. Lose the pressure washer. This is NOT a place where a pressure washer is welcome. That can push water around seals that hold out rainwater/road splash just fine, but won't hold out water at 2000+ PSI. You will get water in all sorts of places where you don't want it. And you will then get corrosion in those same places.
