Solution
Check spark. Remove spark plug. Re-
attach 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.
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, proceed to
next item.
Remove spark plug, turn trimmer so
spark plug hole is aimed at the ground.
Rotate the choke dial to "RUN" posi-
tion and pull starter cord 10 to 15
times. This will clear excess fuel from
engine. Clean and reinstall spark plug.
Pull starter three times with choke dial
at "RUN". If engine does not start,
rotate choke dial to "FULL CHOKE"
position and repeat normal starting
procedure. If engine still fails to start,
repeat procedure with a new spark
plug.
Contact a servicing dealer.
Allow engine to completely warm up. If
engine does not accelerate after three
minutes, contact a servicing dealer.
Contact a servicing dealer.
Use fresh fuel and the correct 2-cycle
lubricant mix.
