CLEANING AND INSPECTING
NOTE: Whenever a part is worn excessively,
cracked, or damaged in any way, replacement is
necessary.

and submerge in carburetor cleaner.
2. Soak for 30 minutes; then rinse with fresh
parts-cleaning solvent.
3. Wash all non-metallic components with soap
and water. Rinse thoroughly.
4. Dry all components with compressed air only
making sure all holes, orifices, and channels are
unobstructed.
5. Inspect the carburetor body for cracks, nicks,
stripped threads, and any other imperfections in
the casting.
6. Inspect the vacuum piston/diaphragm for cracks,
imperfections in the casting, or cracks and tears
in the rubber.
7. Inspect float for damage.
8. Inspect gasket and O-rings for distortion, tears,
or noticeable damage.
9. Inspect tips of the jet needle, pilot screw, and the
needle jet for wear, damage, or distortion.
10. Inspect the slow jet and main jet for obstructions
or damage.

will be extremely lean at idle and part-throttle oper-
ation.
11. Inspect the float valve for wear or damage.

age and tightness.
