Duel fuel

[jdmeth]

I have a Westinghouse 9500 watt duel fuel generator. A year ago when it was new I put about a gallon of gas in it and ran it for an hour and then shut off the fuel so it ran out the carburetor. Every few months I would run it for a few minutes. A few months ago I needed it for a power outage. I put some fresh gas in it and it ran for about five minutes under load and died. It would fire but not continue running. Figuring the carburetor was clogged I hooked up a LP tank. It ran about 15 seconds and died again. Again it will fire but not continue running. Any ideas?

Yep.....suggestion!
Get a dual fuel generator.
Your fuel may be dueling with the generator engine.

I am not really familiar with that unit, but seeing as how it shut down on both fuels, maybe there is a problem with the generator output. Is it being over-loaded or perhaps the mains/standby switch is not working.

Low oil shutoff maybe?.............Mike

How long does the engine run when not under load?

Does not run at all, just revs enough to disengage starter.

As suggested, check the low oil/ low oil pressure sensor. Found my Generac doing this and turned out to be the oil pressure sensor was clogged. Badly designed sensor appearently as a lot of people had the same problem. I just ended up bypassing it.
