Thanks for your reply. It would be more accurate to refer to ethanol corrosion deposits. Since ethanol is acidic and hygroscopic, and increases electrical conductivity of the fuel blend, and carburetors are made from aluminum/zinc alloys, use of ethanol/gas blends used in small engine fuel systems set up a highly corrosive environment in the carb. Oak Ridge labs has an excellent report documenting how corrosion and elastomeric softening happens in engines and fuel systems fueled with ethanol blends.
