Troubleshooting
When problems occur, first check for simple reasons for a problem: for example, an empty fuel tank or the fuel
shut-off valve is turned off. Additional troubleshooting tips can be found in the troubleshooting table.
NOTE:
Do not attempt to service or replace major engine components, or any items that require special timing
or adjustment procedures. This work should be performed by a Kohler Engine Service Center.

stabilized fuel has entered the carburetor.
To empty the system, run the engine until the
tank and system are empty.

Before transporting the engine, ensure the fuel
valve (A) is in the OFF position to prevent fuel
spillage. See Figure
