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.
