Alcohol would be alright IF they made the engine to run it,but it's designed for gasoline and 2-stroke oil with a minimum ,(up to 10%),of ethanol blended into the gas. Thanks for the info.,Fred! I always knew it was corrosive,but that explanation makes more sense. But,Chuck, if you're havin' fun,and don't mind a total rebuild every once in a while, then enjoy your toy! One thing I would wonder is how well did it start when cold? Did you have to always use ether when first starting it cold? Do you live in a pretty warm climate? don-ohio (:^)
