Tvov, there would have been no reason to add the stabilizer to it if I ran the generator out of fuel but there's two schools of thought on whether to drain the fuel out or add stabilizer and leave it. I've done it both ways. Neither caused me any issue. One theory is that if you leave fuel in the machine, it may gum up the carb anyway. The other is if you run it completely out of fuel it can cause damage to the engine. I don't know if either is true and wouldn't say either way was right or wrong. It all depends on whose reports you believe.
