Remember too that even though the alcohol/water mixture will burn, it produces poor power due to its low calorie content. Engines running pure alcohol must use very large carburetor jets to get the same power output as gasoline. They also get fewer mpg on alcohol because of the greater consumption due to less energy per gallon. Add some water to the alcohol and it just makes matters worse. The only advantage of water being used in an engine (water injection, not in the tank) is to reduce the chances of severe detonation under load when using high compression or forced induction. The steam produced by the water actually robs the engine of some power due to the large amount of energy needed to vaporize water. I still maintain that any water in your Ercoupe's fuel system will only cause trouble and a quick fix with alcohol additives will only cause you problems in the future.
