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 radiator and

engine.

2. Change the oil and filter while the engine is still

warm from operation. See “Change Oil and Filter”

on page 9.

3. The coolant (anti-freeze) mixture should be in good

condition and tested to guard against freezing in

cold temperatures. The recommended equal parts

mixture will normally provide protection down to

temperatures of -37°C (-34°F). If storage

temperatures will fall below this, the cooling system

should be drained. A note should then be attached

to the equipment and/or engine as a reminder to

refill the cooling system before starting.

4. 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.

5. 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.

6. 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 5.

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.
