I would say if the gas dont smell funky throw in about 7 or 8 oz of sea foam or berrymans b12. I have read in more than a few times that the alcohol blended fuels after they sit extended time will loose some octane. Probably not to bad for your mower, but trying to light of a higher compression engine might be tough. I agree with the pull the plugs, shot of some kind of light oil, trans fluid marvel mystery oil or something. Then spin it over.
