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 RUN and pull the
starter cord 10 to 14 times. This clears excess fuel
from the engine. Clean and reinstall the spark plug.
With the trigger fully depressed, pull the starter
cord 3 times. If the engine does not start, set the
choke lever to FULL and follow normal starting
instructions. If the engine still fails to start, repeat
the procedure with a new spark plug.
5. Contact an authorized service dealer.
1. Use fresh fuel and the correct 2-cycle oil mix.
2. Clean the air filter.
3. Clean the spark arrester.
1. Lubricate with silicone spray.
2. Install more line.
3. Pull line while alternately pressing down on and
releasing the retaining cap.
4. Remove line from spool and rewind.
5. Advance line at full throttle.
Clean the threads and lubricate with grease. If this does
not solve the problem, replace the retaining cap.
