Note: This engine complies with EPA (Environmental Protection Agency) and CARB
*
(California Air Resource Board) regulations which require exhaust emission control.
As a result, 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 purchase, the unit should be taken to a factory authorized
service center for repair. In most cases, the needed adjustment is a simple task for
the factory trained service representative.
Solution
1. Check spark. Remove spark plug. Reattach
the spark plug cap and lay spark plug on
metal 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).
3. Remove spark plug, turn trimmer so spark
plug hole 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 proce-
dure. If engine still fails to start, repeat proce-
dure with a new spark plug.
4. Contact a servicing dealer.
*Turn "L" needle (A) counterclockwise 1/16
turn. If "L" low needle (A) can not be turned
counterclockwise, do not force plastic limiter
caps. Contact a servicing dealer.
*Turn "H" needle (B) counterclockwise 1/16
turn. If "H" high needle (B) can not be turned
counterclockwise, do not force plastic limiter
caps. Contact a servicing dealer.
1. Use fresh fuel and the correct 2-cycle oil
mix.
2. Clean per instructions in Maintenance Sec-
tion.
3. Turn "H" (B) needle clockwise
1/16 turn.
4. Contact a servicing dealer.
