Cleaning and Inspection
Debris, gum, water and carbon contamination in the
carburetor or on the exterior moving parts of the carbu
retor are often responsible for unsatisfactory engine
performance. Efficient carburetion depends upon care
ful cleaning and inspection.
The cleaning and inspection procedure listed below
does not involve the replacement parts included in the
carburetor overhaul/repair kit. Install all gaskets and
parts included in the repair kit when the carburetor is
assembled. Discard the original gaskets and replaced
parts.
CAUTION: Do not use a wire brush to clean any parts.
Do not use a drill or wire to clean any openings or
passages in the carburetor. A drill or wire may enlarge
the hole or passage and change the calibration of the
carburetor.
CAUTION: Do not immerse any part of the altitude
compensation assembly in cleaning solvent. Wipe all
parts with clean, lint-free cloths.
Wash all the carburetor parts except accelerator
pump diaphragm, power valve, vacuum modulator dia
phragm dashpot assembly and altitude compensation
assembly in clean commercial carburetor cleaning sol
vent. If a commercial solvent is not available, use lac
quer thinner or denatured alcohol. If a commercial
cleaner is used, rinse the parts in hot water to remove all
traces of the cleaning solvent, then dry them with com
pressed air. Wipe all parts that cannot be immersed in
solvent with a clean, soft, dry cloth. Ensure all sedi
ment, gum, carbon and other foreign matter is removed
from all parts. Force compressed air through all pas
sages of the carburetor.
Examine the choke shaft for wear and excessive loose
ness or a binding condition. Inspect the choke shaft and
polish with fine crocus cloth or equivalent material.
