SOLUTION
1. Set switch to the I (ON) position.
2. Remove the spark plug. Reattach the spark plug
cap and lay the spark plug on the metal cylinder.
Pull the starter cord and watch for a spark at the
spark plug tip. If there is no spark, repeat the test
with a new spark plug.
3. Push primer bulb until the bulb is full of fuel. If the
bulb does not fill, the primary fuel delivery system
is blocked. If the primer bulb fills, the engine may
be flooded. (See next item.)
4. Remove the spark plug. Turn the product so that
the spark plug hole is aimed at the ground. Make
sure the choke lever is set to position B and pull
the starter cord 10 to 14 times. This clears excess
fuel from the engine. Clean and reinstall the spark
plug. With the throttle trigger fully depressed, pull
the starter cord 3 times. If the engine does not
start, set the choke lever to A and follow normal
starting instructions. If the engine still fails to start,
repeat the procedure with a new spark plug.

1. Use fresh fuel and the correct 2-stroke oil mix.

the Maintenance section.
