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
fill, primary fuel delivery system is blocked. Contact a
service dealer. If primer bulb fills, engine may be flooded
(see next item).
Remove spark plug, turn trimmer so spark plug hole is
aimed at the ground. Make sure lever is in the open choke
position 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 close
choke position and follow normal starting instructions in
"STARTING AND STOPPING" section. If engine still fails
to start, repeat procedure with a new spark plug.
