I agree Seafoam may help but since you draw the gas from the same gas tank as your engine you will need tto treat all of the gas and that is relatively expensive.

There is still a small amount left in the bottom of the bowl but at least not a few ounces as would normally be. It takes about 20 seconds of cranking the generator to refill the bowl the next time I start it.
