Onan 4kw white smoke won't run, gas running out

Just filled up my Class C motorhome as we are getting ready for a trip. The MH and Onan generator are less than 1 year old and has been run a few times a month while camping under load or exercised.
Ran the generator yesterday for 2 hours with air conditioner running while we did some interior work. Now this afternoon, it wouldn't start. It cranks with white smoke and fuel was dripping from the air filter housing.

    Probably a stuck float or a little grit.
    Get a one gallon gas can and put some seafoam and gas in it and put the gas line in the can. Run the genny for a while,

    Thought it might be a stuck float or something. I tried using some vise grips to clamp off the fuel and it started running better when now more white smoke, I released the vise grips and now it's running fine. Have the air conditioner running to cool it down so we can finish packing.
    Any ideas???????
