SOLUTION
Set switch to the I (ON) position.
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.
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.)
Ensure on/off switch is set to the off position.
Remove the spark plug from the engine and the
spark plug boot. Turn the product so that the spark
plug hole is aimed at the ground. Make sure the
choke lever is set to 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 and follow normal starting
instructions. If the engine still fails to start, repeat
the procedure with a new spark plug.
