About two weeks ago, I decided to fix the annoying little drip from the bathroom sink drain in the Tiger. I don't use that tiny sink, but it gets water in it when I shower, so has to be re-winterized each year, and it drips then.

So I turned on the LP furnace to start knocking the chill off, then plugged in the Onan and started it. After it was warmed up, I tried to use the 1500 watt electric heater... oops! The 2800 watt Onan wouldn't carry that load... it'd run rough, then stall. It acted sort of like it was the fuel filter.... run for a while under load, stumble, stall, but be OK to restart almost immediately.

I went ahead and found the drip and fixed it; too dam' cold outside to work on the Onan. The triangular gasket was broken on the shorter leg of the P trap. Some non-hardening sealer was all it took, since there was no way to get a new gasket on it.

When it warmed up a few days later, I replaced the Onan's fuel filter (a real PITA; you can't see the lower clamp). Nope, same symptoms, so it wasn't that. Darn!

I finally remembered that there's a spark arrestor screen in up inside the exhaust. Once I got to it and cleaned it, all was fine.

Dunno if the 4.0 & 3.6LP Onans that are common in class C's have a spark arrestor screen, but I suspect they do. So y'all may want to remember this as a maintenance item every year or few hundred hours.

Jim, "The wages of sin is death. But after they get done taking out taxes, it's just a tired feeling."

So after you replaced the spark arrestor screen Then it would run the 1500 watt heater.????
