Battery Charging

WARNING: Explosive Gas!

Batteries produce explosive hydrogen gas while being charged.
To prevent a fire or explosion, charge batteries only in well
ventilated areas. Keep sparks, open flames, and other sources of
ignition away from the battery at all times. Keep batteries out of
the reach of children. Remove all jewelry when servicing
batteries.

Before disconnecting the negative (-) ground cable, make sure
all switches are OFF. If ON, a spark will occur at the ground
cable terminal which could cause an explosion if hydrogen gas
or gasoline vapors are present.

NOTE: Do not apply 12 volt DC to kill terminal of

ignition module.

Fuel System

Fuel Filter

Most engines are equipped with an in-line fuel filter.
Periodically inspect the filter and replace with a
genuine Kohler filter 

seasonally or every 150

operating hours

.

Fuel Line

These engines use Low Permeation SAE 30 R7 rated
fuel line; certified to meet emission requirements.
Standard fuel line may not be used. Order
replacement hose by part number through a Kohler
Engine Service Dealer.

Figure 25. Keihin Two-Barrel Carburetor.

NOTE: Carburetor adjustments should be made

only after the engine has warmed up.

NOTE: To ensure correct engine operation at

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.

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

gasoline.

• Make sure the fuel tank cap vent is not blocked

and that it is operating properly.

• If the fuel tank is equipped with a shut-off valve,

make sure it is open.

• If the engine is equipped with an in-line fuel filter,

make sure it is clean and unobstructed. Replace
the filter if necessary.

Carburetor Troubleshooting and
Adjustments

These engines use a Keihin BK two-barrel carburetor
with fixed main jets, and fixed or limiter-equipped
low idle fuel adjusting needles. See Figure 25. In
compliance with government emission standards, the
carburetor is calibrated to deliver the correct fuel-to-
air mixture to the engine under all operating
conditions. Adjustments are made as follows.
