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

gasoline, or refueled with bad gasoline.
Battery is not charged.

Item plugged in is defective.
An occasional light "knocking" or "pinging"
under heavy load is not a cause for concern.
However, if the knocking or pinging oc-
curs under normal load at a steady engine
speed, the problem may be with the brand
of gasoline being used.
