Solution
1.
Remove the spark plug. Reattach
the spark plug cap and lay the
spark plug on the metal cylinder.
Pull the starter grip and rope 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 delivery 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 RUN and
pull the starter grip and rope 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 grip and rope 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 proce-
dure with a new spark plug.

dealer.
