Fuel Filter
The filter of the LP fuel system is an integral part within
the lock-off/filter assembly. All service relating to the
lock-off/filter is to be performed by an authorized Kohler
Engine Service Dealer or qualified LP personnel only.
Servicing of filter is recommended every 500 hours. The
gasoline system (dual-fuel only) has an in-line fuel filter.
Periodically inspect the filter and replace when dirty. Use
a genuine Kohler filter, Part No. 24 050 02-S.
Carburetor Troubleshooting and
Adjustments
In compliance with government emission standards,
the carburetor and the regulator are calibrated and
preset to deliver the correct fuel-to-air mixture to the
engine under all operating conditions and cannot be
adjusted, except for low idle speed. Carburetor
servicing is to be performed by an authorized Kohler
Engine Service Dealer only. See Figure 11.

In compliance with government emission standards,
the regulator is preset at the factory to provide the
proper supply of fuel. No adjustment or resetting of
regulator is to be made. All service relating to the
regulator must be performed by an authorized Kohler

Over time, fuel deposits can accumulate inside the
regulator. Draining of these deposits is recommended
(Nikki regulators only) every 500 operating hours, or
annually, whichever comes first.
