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 8.
.
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 manufacturer's
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 plugs,
but do not connect the plug leads. Crank the
engine two or three revolutions.
