Low Idle Fuel Setting.
Low Idle Speed Setting: Place the throttle control
into the "idle"
or "slow"
position. Set the low idle
speed to 1500 RPM* (_+75 RPM) by turning the
low idle speed adjusting screw in or out. Check
the speed using a tachometer.
*NOTE: The actual low idle speed depends on the
application - refer to equipment
manufacturer's
recommendations.
The
recommended
low idle speed for basic
engines is 1500 RPM. To ensure best
results when setting the low idle fuel
needle, the low idle speed must not
exceed 1500 RPM (+ 75 RPM).
Troubleshooting
When troubles occur, be sure to check the simple
causes which, at first, may seem too obvious to be
considered. For example, a starting problem could be
caused by an empty fuel tank. Some common causes
of engine troubles are listed in the following table.
Do not attempt to service or replace major engine
components, or any items that require special timing or
adjustment procedures. Have your Kohler Engine
Service Dealer do this work.

Storage
If the engine will be out of service for two months or
more, use the following storage procedure:
1. Clean the exterior surfaces of the engine.
2. Change the oil and filter while the engine is still
warm from operation. See "Change Oil and Filter"
on page 9.
The fuel system must be completely emptied, or
the gasoline must be treated with a stabilizer to
prevent deterioration. If you choose to use a
stabilizer, follow the manufacturers
recommendations,
and add the correct amount for
the capacity of the fuel system. Fill the fuel tank
with clean, fresh gasoline. Run the engine for 2-3
minutes to get stabilized fuel into the carburetor.
To empty the system, run the engine until the tank
and system are empty.

Due to the deep recess around the spark plug,
blow out the cavity with compressed air. Remove
the spark plug. The spark plug is most accessible
when the blower housing is removed for cleaning.
Add one tablespoon of engine oil into the spark
plug hole. Install the plug, but do not connect the
plug lead. Crank the engine two or three
revolutions. Connect the plug lead.
5. Reinstall the blower housing, if removed
previously, and torque the blower housing screws
to 7.5 N.m (65 in. lb.).
6. Store the engine in a clean, dry place.
