Inspection/Repair
To clean vent ports, internal circuits 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 tab. Check the float hinge and pin
for wear or damage.

damage.
• The choke plate is spring loaded. Check to make
sure it moves freely on the shaft.
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.
Refer to the Parts Manual for the engine being
serviced to ensure the correct repair kits and
replacement parts are used. The Kohler part number is
stamped on the top of the carburetor mounting flange.
