Onan Gen Set 4000 (1990's)	Alex	2-22-08
I have a Onan GEN SET 4000 in my 1993 Winnebago 22' RV. Runs on gas. Recently the fuel seems to be mixing with the oil. What can cause this to happen? Also, if I need to replace it, what generators (good priceand reliable) are the same size / compatible and would be able to fit in the same space? Thanks.

Sounds like the float has a hole in it and sunk --flooding the intake--gas running douw intake and around pistons- to crankcase--- rich in va.
