screw gasket, and bowl retaining screw or fuel
solenoid.
Torque the bowl retaining screw to 5.1-6.2 N·m
(45-55 in. lb.).
Fuel Shut-off Solenoid
Many engines are equipped with a fuel shut-off
solenoid installed in place of the bowl retaining screw
to eliminate backfiring when the engine is shut down.
If backfiring occurs on engines equipped with this
solenoid, verify that the correct shutdown procedure
is being used. In order for the solenoid to be effective,
the engine must be running between half and full
throle when the key is turned off. Next, check the
baery to ensure that it is not discharged or faulty. A
minimum of 7.3 volts DC is required to activate the
solenoid. Also check to see that the ground lead from
the carburetor body to the air cleaner base mounting
screw is properly connected.
If these check out, the solenoid should be removed for
bench testing. Remember to shut off the fuel supply
and catch any fuel spilling from the carburetor as the
solenoid is removed.
Bench test the solenoid by grounding the solenoid
case and applying 12 volt DC to the spade terminal. If
the plunger does not retract, the solenoid is faulty and
must be replaced. Always use a new fuel bowl gasket
whenever the solenoid is installed. Refer to the wiring
diagram in Section 7 and connect the fuel shut-off
solenoid.

High Altitude Operation
Operating the engine with the wrong engine
configuration at a given altitude may increase
its emissions and decrease fuel efficiency and
performance. To ensure correct engine operation
at altitudes above 1219 meters (4000 ), 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.
To obtain high altitude kit information or locate a
dealer near you, call 1-800-544-2444 to find the names
of the nearest Kohler Co. Service Centers or, access
our web site at: www.kohlerengines.com and click on
the “Service & Dealer Locator” located in the upper
right hand corner. The service center will need your
engine specification number which is found on your
Engine ID Label.
Unitized Throttle and Choke Control
Some engines are equipped with a unitized throle
and choke control. This assembly controls the choke
and engine speed with a single lever. See Figure 5-12.
