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 common causes of troubles. Do not attempt to service or replace major items or any items that call for special timing or adjustment procedures (governor, valves, etc.). Have this work done by your Engine Service Dealer.
