vent thoroughly, use a good carburetor solvent
(like Gumout
). Blow clean compressed air
through the idle adjusting needle hole. Be careful
to use a suitable shop rag to prevent debris from
hitting someone.
8. Remove the preformed rubber gasket only if it is
to be replaced. If it is removed for any reason,
replace it.
Inspection/Repair
Carefully inspect all components and replace those
that are worn or damaged.
Inspect the carburetor body for cracks, holes and
other wear or damage.
Inspect the float for cracks, holes, and missing or
damaged float tabs. Check the float hinge and
shaft for wear or damage.
Inspect the fuel inlet needle and seat for wear or
damage.
Inspect the tip of the low idle fuel adjusting needle
for wear or grooves.
The choke plate is spring loaded. Check to make
sure it moves freely on the shaft.
NOTE: The choke and throttle plate assemblies
are staked and matched to the shafts at
the factory. They are not serviceable
items.
Always use new gaskets when servicing or reinstalling
carburetors. Repair kits are available which include
new gaskets and other components. These kits are
described on the next page.
