TROUBLESHOOTING

POSSIBLE CAUSE
Engine switch is OFF.
No fuel.
Stale gasoline or water in gasoline.
Lubricant level is low.
Fuel valve is OFF.
Spark plug faulty, fouled, or improperly
gapped.
Choke is in RUN position.
Engine stored without treating or
draining gasoline, or refueled with bad
gasoline.
Dirty fuel filter.
Water in gasoline.
Weak spark at spark plug.
Dirty air filter.
Engine stored without treating or
draining gasoline, or refueled with bad
gasoline.
Battery wires are disconnected.
Battery is not charged.
Engine battery charge circuit fuse is
blown.
Circuit breaker is tripped.
GFCI is tripped.
Item plugged in is defective.
An occasional light "knocking" or "ping-
ing" under heavy load is not a cause
for 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 be-
ing used.
