TROUBLESHOOTING

POSSIBLE CAUSE
No fuel.
Stale gasoline or water in gasoline.
Lubricant level is low.
Fuel valve is OFF.
Spark plug faulty, fouled, or improperly
gapped.
Choke lever is in RUN position.
Engine stored without treating or
draining gasoline, or refueled with bad
gasoline.
Dirty fuel filter.
Water in gasoline.

Air filter element clogged.
Engine stored without treating or
draining gasoline, or refueled with bad
gasoline.
Circuit breaker is OFF.
Item plugged in is defective.
An occasional light "knocking" or "ping-

concern. However, if the knocking or
pinging occurs under normal load at a
steady engine speed, the problem may
be with the brand of gasoline being used.
