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 of
adjustments procedures (such as valves, governor, etc.). Have this work done
by your Engine Service Dealer.
