I've heard some 'smokin' people in and around TN like to alter the gas mix with some Jack Daniels whiskey to negate the effects of ethanol? Might work?
Seafoam comes in I think 16 oz. can and have used up to the whole can once with my 6.9 gallon I/S tank when full since it ran like crap when I bought it all gunked up, but usually only put in an ounce or less per gallon at most only a few times per year. Definitely a must to put in full tank before winter storage and run it a few miles around town with seafoam, etc. in the tank to get into carbs.
