Exmark Metro HP Operator's Manual page 34

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.
