: Gasoline is explosive; work in a well-ventilated area away from sparks. Because these carburetors are no longer in production,

Remove the top cap (4 screws). Carefully lift out the vacuum piston/diaphragm assembly. Do not use solvent on the diaphragm. Use only soapy water. Soak the metal body in carb cleaner for 4 hours, but remove all rubber first. Carefully lift out the vacuum piston/diaphragm assembly
