    Default Lots of fuel in Onan oil pan?

    I have a 77 motorhome with a carburated onan generator. fuel is getting into the oil pan and quits after about 10 minutes of running. we drained the oil (that now has gas in it), put in a fresh quart of oil and run it for a while then sure enough more gas in the oil pan. any ideas? bad seals or rings? any good RV mechanics in Wasilla?

    I have seen where the fuel pump had a hole in the diaphragm causing this problem on other makes of engines.
    I don't mean to sound bitter, cold, or cruel, but I am, so that's how it comes out.
