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 Oil
Filter" on page 9.
3. 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.
Close fuel shut-off valve when unit is being stored
or transported.
To empty the system, run the engine until the tank
and system are empty.
4. Remove the spark plugs. Add one tablespoon of
engine oil into each spark plug hole. Install the
plugs, but do not connect the plug leads. Crank the
engine two or three revolutions.
5. Store the engine in a clean, dry place.

Parts Ordering
The engine Specification, Model, and Serial Numbers
are required when ordering replacement parts from your
Kohler Engine Service Dealer. These numbers are found
on the identification plate which is affixed to the engine
shrouding. Include letter suffixes if there are any. See
"Engine Identification Numbers" on page 6.
Always insist on genuine Kohler parts. All genuine
Kohler parts meet strict standards for fit, reliability, and
performance.
Major Repair
Major repair information is available in Kohler Engine
Service Manuals. However, major repair generally
requires the attention of a trained mechanic and the use
of special tools and equipment. Your Kohler Engine
Service Dealer has the facilities, training, and genuine
Kohler replacement parts necessary to perform this
service. For Sales & Service assistance call
1-800-544-2444 (U.S. & Canada) or contact your
Kohler Engine Dealer or Service Distributor, they're in
the Yellow Pages under Engines-Gasoline.
