Solution
1.
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.
2.
Push primer bulb until the bulb is full of fuel.
If the bulb does not fill, the primary fuel deliv-
ery system is blocked. If the primer bulb fills,
the engine may be flooded. (See next item.)
3.
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
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 instruc-
tions. If the engine still fails to start, repeat the
procedure with a new spark plug.
