(See Figures 172, 173, 200 and 201)

NEVER dip rubber parts, plastic parts, or nylon parts, in carburetor cleaner. These parts should be cleaned ONLY in solvent and then blown dry with compressed air. Place all metal parts in a screen-type tray and dip them in carburetor cleaner until they appear completely clean; then wash with solvent, or clean water, and blow dry with compressed air. Blow out all passages in the castings with compressed air. Check all parts and passages to be sure they are not clogged or contain any deposits. NEVER use a piece of wire or any type of pointed instrument to clean drilled passages or calibrated holes in a carburetor. Move the throttle shaft back-and-forth to check for wear. If the shaft appears to be too loose, replace the complete throttle body because individual replacement parts are NOT available. Inspect the main body, airhorn and venturi cluster gasket surfaces for cracks and burrs which might cause a leak. Check the float for deterioration. Check to be sure the float spring has not been stretched. If any part of the float is damaged, the unit must be replaced. Check the float arm needle contacting surface and replace the float if this surface has a groove worn in it. Inspect the tapered section of the idle adjusting needles and replace any that have developed a groove. Check the orifices for cleanliness. The orifice has a stamped number. This number represents a drill size. Check the orifice with the shank of the proper size drill to verify the proper orifice is used. The local dealer will be able to provide the correct size orifice for the engine and carburetor being serviced.
