Use SeaFoam to stabilize your ethanol gas. I just got a ATV out, it sat over a year with gas treated with SeaFoam, ethanol. I drained the gas, but didn't touch the carb. Gas looked good, I dumped it in my company trucks. ATV fired right up. That wasn't the case before SeaFoam. The brass pieces in the carb would corrode shut. Iam a true believer in Sea Foam after that. The
