Carburetor Troubleshooting and
Adjustments
Engines in this series use either a single barrel or two
barrel carburetor depending on model, and may also
be equipped with a Governed Idle System. Specific
adjustment procedure(s) are provided based on the
model and carburetor involved. If the engine is
equipped with a Governed Idle System, refer to
Models with Governed Idle System when performing
any carburetor adjustment, as an additional step to
the listed procedure(s) is required.
NOTE: Carburetor adjustments should be made
only after the engine has warmed up.
The carburetor is designed to deliver the correct
fuel-to-air mixture to the engine under all operating
conditions. The high speed mixture is set at the factory
and cannot be adjusted. The low idle fuel adjusting
needle (if equipped) is also set at the factory and
normally does not need adjustment.
NOTE: To ensure correct engine operation at

Troubleshooting
If engine troubles are experienced that appear to be
fuel system related, check the following areas before
adjusting the carburetor.
• Make sure the fuel tank is filled with clean, fresh
• Make sure the fuel tank cap vent is not blocked
• If the fuel tank is equipped with a shut-off valve,
• If the engine is equipped with an in-line fuel filter,
altitudes above 1525 meters (5000 ft.), it may
be necessary to have an authorized Kohler
dealer install a special high-altitude jet kit in
the carburetor. If a high-altitude kit has been
installed, the engine must be reconverted to
the original jet size, before it is operated at
lower altitudes, or overheating and engine
damage can result.
