cylinder. Pull the starter rope and watch for spark
at spark plug tip. If there is no spark, repeat test
with a new spark plug.
2.Push primer bulb until bulb until fuel is visible in the
bulb. If fuel is not apparent, the primary fuel
delivery system is blocked. Contact a servicing
dealer. If primer bulb fills, engine may be flooded
(see next item).

is aimed at the ground. Move choke lever to “RUN”
and pull starter cord 10 to 15 times. This will clear
excess fuel from engine. Clean and reinstall spark
plug. Pull starter three times with choke lever at
“RUN”. If engine does not start, move choke lever
to “CHOKE” and repeat normal starting procedure.
If engine still fails to start, repeat procedure with a
new spark plug.

Turn "H" needle counterclockwise 1/16 turn. If “H”
high needle can not be turned counterclockwise, do
not force plastic limiter caps. Contact a servicing
dealer.
See Figure 14.
1. Use fresh fuel and the correct 2-cycle oil mix.
2. Clean air filter, refer to “Replacing and Cleaning
the Air Filter” earlier in this manual.
3. Turn “H” (B) needle clockwise 1/16 turn. See Fig-
ure 14.
4. Contact a servicing dealer.
Turn idle speed screw clockwise to increase idle
speed.
See Figure 14.
NOTE: The carburetor adjustment needle(s) are equipped
with plastic cap(s) that prevents counterclockwise rotation
from the original factory adjustment. If your unit exhibits
specific performance problem(s) where the Trouble Shooting
Section recommends a counterclockwise needle adjustment
and no adjustments have been made since original pur-
chase, the unit should be taken to a factory authorized
service dealer for repair. In most cases, the needed adjust-
ment is a simple task for the factory trained service repre-
sentative.
