Tighten low speed screw until a slight resistance
is felt. Then, back it off to the specification as per
following chart.
NOTE: Turning screw clockwise leans mixture and
turning screw counterclockwise enriches mixture.
Start and warm up engine.
Check that engine idles and runs smoothly. Make
sure engine reacts quickly to throttle lever depres-
sion. If necessary, readjust low speed screw
(± 1/4 turn).
NOTE: On twin carburetor engines, both low
speed screws must be adjusted exactly the same
way. Never adjust screws more than 1/4 turn at a
time.

The high speed screw is sealed with a plastic cap
that allows an adjustment of 1/4 turn.
NOTE: Turning screw 1/4 turn counterclockwise
enriches mixture and turning screw clockwise
