ENGINE TROUBLESHOOTING
When a problem occurs, do not overlook the simple causes. For example, starting
problems could be caused by an empty fuel tank. The following tables list some of
the common causes of trouble. Do not attempt to service or replace major items or
any items that call for special timing or adjustment procedures (such as valves,
governor, etc.). Have this work done by your Engine Service Dealer.
