Before disassembling the carburetor, drain the fuel bowl and
clean the outside of the carburetor thoroughly with solvent. All
work should be done on a clean surface. Care should be
taken when disassembling the carburetor or removing the jets.
Most carburetor malfunctions are due to wear or clogging of
internal passages with foreign material.
Do NOT
bend the
float pin during removal. See ‘Carburetor Troubleshooting’
elsewhere in this section.
Remove the float bowl (1) by removing the retaining
screw (2) and washer (3) (Ref. Fig. 7).
Inspect the bowl gasket (4) for nicks or cuts. Carefully
press out the float pin (5), remove the float (6) and the
inlet valve (7). Inspect the inlet valve for wear at its tip.
Remove the main jet (8).
Wash all parts in solvent and blow through all passages
with compressed air. Replace all gaskets and any parts
which show significant wear or damage. Drain screw (9)
and spring (10) can be used to drain the fuel from the
bowl without removing the bowl.
