Troubleshooting
When troubles occur, be sure to check the simple causes which, at first, may seem to 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.
