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 table lists 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.
