I'm starting to wonder if this is good, bad, or overkill for my generator. I keep Sta-bil in it, but there's a tiny overflow hole in the carburetor float bowl, so the gas in the bowl is exposed to air. After its monthly exercise, I turn off the fuel valve and after about a minute it burns off what's in the float bowl. It takes a good 10 seconds of cranking with the electric starter before it fires up the next time, despite a several pumps on the primer. Would I be better off leaving the float bowl full and trust the Sta-bil to keep the fuel from getting gummy?
