OK, thanks for all the info. Yes, it was set for high altitude, don't know how that was, but moved it back to about 2000 feet. No change
Cleaned the fins real good. No change.
It starts right up cold, runs great for about 20 minutes then quits, won't start again till it cools down. then runs about 15 minutes quits again.
Still looking for the fuel pump, according to the booklet it's electric, when you prime you can hear it running. Tried to get an RV place yesterday to check it out. He informed me he doesn't do any thing to them except change the oil and didn't know any place close by that works on them. I sure hate to drive all the way to Dallas but if all else fails maybe I will. Thanks again.
