Solution
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.
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 product so
spark plug hole is aimed at the ground.
Rotate the choke dial to "RUN" position
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
