Solution
The spark plug may be damaged, remove it and check for
dirt and cracks. Replace with a new spark plug.
Push primer bulb until bulb is full of fuel. If bulb does not
fi ll, primary fuel delivery system is blocked. Contact a
service dealer. If primer bulb fi lls, engine may be fl ooded
(see next item).
Remove spark plug, turn trimmer so spark plug hole is
aimed at the ground. Make sure lever is in the
and pull starter cord 10 to 14 times. This will clear excess
fuel from engine. Clean and reinstall spark plug. With
the throttle trigger fully depressed, pull starter cord three
times with the lever at open choke position. If engine
does not start, move choke lever to
follow normal starting instructions in "STARTING AND
STOPPING" section. If engine still fails to start, repeat
procedure with a new spark plug.
