DUROMAX Dual Fuel XP13000HX

[Gebo]

My year old generator will start and run on propane. Won’t start on gasoline. I only use non ethanol 93 octane stabilized fuel.

I started it this fall on gas setting and it ran fine. Now it won’t.

Spark plug was wet with gas when I pulled it out.

What is my next step?

The jets in the carb and clogged. The propane doesn't use the carb jets but the gasoline does.
Either remove the carb and clean the jets out or buy a new carb.

If the spark plug is wet with gas, it's probably flooding, which would be the opposite result of clogged jets. Look to make sure the float valve isn't stuck open or blocked by dirt. Should be able to unscrew the float bowl. Lift up the float gently and make sure fuel stops trickling out.

Well, I bypassed the valve that switches from propane to gas. I ran fuel line directly from tank to carb. It started right up. So, the problem is in that switch. Gonna call DUROMAX and get me a new switch.
