Do you guys do anything to negate the harmful effects of 10% Ethanol in the gas we get now ? I can't find any local "no ethanol" stations. Do you put additives in your gas mix ? If so, what ? I know I have six saws, and keep them well maintained, and only 2 are running worth a derned. I just don't have the time to pull all of the carbs., impulse lines, fuel lines, etc... I'm fairly confident the ill-effects are from the ethanol in the fuel mix.
