ENGINE TROUBLESHOOTING
When a problem occurs, do not overlook the simple causes. For example, starting
problems could be caused by an empty fuel tank, key switch not "ON" etc. 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.
