5. Starter cord pulls harder now
then when new
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
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 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.
