CLEANING
Cleaning must be done with carburetor disassembled. Soak parts long
enough to soften and remove all foreign material. Use a carburetor
solvent, lacquer thinner or denatured alcohol. Make certain the throttle body is free of all hard carbon deposits. Wash off in suitable MIvent. Blow out all passages in castings with compressed air and check
carefully to insure thorough cleaning of obscure areas.
CAUTION: Do not soak pans containing rubber or plastic material.
Serious damage could result.
Fuel bowls, should only be exposed to carburetor cleaner long enough
to permit removal of gum and varnish deposits with a brush. (NOTE:
Some fuel bowls have internal "0" ring seals which are not
removable, but can be damaged by prolonged exposure to some carburetor cleaning solvents.)
