Cleaning and Inspection
1. Obtain Carburetor Cleaner (Part No.'s 100041 or
100042).
NOTE: Remove and set aside all rubber parts or those
that have rubber components, such as the needle valve,
O-rings, and fuel hose, as these can be damaged by
the carburetor cleaner.
2. Inspect carburetor body and float bowl for sediment,
gum or varnish deposits. Spray parts and then wipe
away cleaning solution with a clean cloth. Repeat step
until clean cloth shows no evidence of dirt or debris.
3. Inspect carburetor body and float bowl for cracks or
other damage. Replace carburetor if either condition is
observed.
4. Locate each fuel and air passageway in the carburetor
body. Look for the brass or bronze beads in the casting,
which point out where the cross drillings of the
passageways are located.
5. Spray carburetor cleaner into the entrance of each
passageway and look for the solution to exit from one
or more passageways.
6. Use carburetor cleaner and compressed air to ensure
that each passageway is clean and open.
NOTE: Avoid use of wires or pointed tools as they can
scratch or damage surfaces, enlarge holes, and push
grit and dirt deeper into carburetor.
7. Look through the main jet while holding it up to the light.
The hole should appear round and unobstructed.
Thoroughly clean with carburetor cleaner and
compressed air.
8. Hold emulsion tube up to the light to verify cleanliness.
Verify that all orifices at sides of emulsion tube are clean
and open.
9. Check emulsion tube/main jet passageway for
discoloration, dirt, and debris. Clean passageway with
a soft bristle gun cleaning brush.
10. Use compressed air to clean atmospheric vent holes
and air/fuel jets embedded in the carburetor body.
