SOLUTION
1. Check spark. Remove spark plug. Reattach the
spark plug cap and lay spark plug on metal
cylinder. Pull the starter rope and watch for
spark at spark plug tip. If there is no spark,
repeat test with a new spark plug.
2. Push primer bulb until bulb is full of fuel. If bulb
does not fill, primary fuel delivery system is
blocked. Contact a servicing dealer. If primer
bulb fills, engine may be flooded (see next
item).
3. Remove spark plug, turn trimmer so spark plug
hole is aimed at the ground. Make sure lever is
in the "WARM START" 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 lever at "WARM
START" position. If engine does not start,
move choke lever to "COLD START" and follow
normal starting instructions in "STARTING
AND STOPPING" section. If engine still fails to
start, repeat procedure with a new spark plug.
