Inspection/Repair
To clean vent ports, seats etc., use a good
commercially available carburetor solvent, such as
Gumout™, and clean, dry compressed air to blow out
internal channels and ports. Use a suitable shop rag to
prevent debris from hitting someone.
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 (if equipped), for wear or grooves.
• The choke plate is spring loaded. Check to make
sure it moves freely.
