ENGINE
TO ADJUST THROTTLE CONTROL CABLE
(See Fig. 32)
The throttle control has been preset at the factory and
adjustment should not be necessary. Check adjustment as
described below before loosening cable. If adjustment is
necessary, proceed as follows:
• With engine not running, move throttle control lever to
fast position.
• Check that swivel is against stop. If it is not, loosen
cable clamp screw and pull cable back until swivel is
against stop. Tighten cable clamp screw securely.
TO ADJUST CHOKE CONTROL (See Fig. 33)
The choke control has been preset at the factory and
adjustment should not be necessary. Check adjustment as
described below before loosening cable. If adjustment is
necessary, proceed as follows:
• With engine not running, move choke control (located
on dash panel) to full choke position.
• Loosen knob and remove cover assembly from air
cleaner.
• Choke should be closed. If it is not, loosen casing
clamp screw and move choke cable until choke is
completely closed. Tighten casing clamp screw se­
curely.
• Replace air cleaner cover assembly and tighten knob.
TO ADJUST CARBURETOR (See Fig. 34)
The carburetor has been preset at the factory and adjust­
ment should not be necessary. However, minor adjust­
ment may be requi red to COmpensate for differences in f uel,
temperature, altitude or load, if the carburetor does need
adjustment, proceed as follows:
In general, turning the mixture screw in (clockwise) de­
creases the supply of fuel to the engine giving a leaner fuel/
air mixture. Turning the mixture screw out (counterclock­
wise) increases the supply of fuel to the engine giving a
richer fuel/air mixture.
IMPORTANT: DAMAGE TO THE NEEDLES AND THE
SEATS IN CARBURETOR MAY RESULT IF SCREW IS
TURNED IN TOO TIGHT.
PRELIMINARY SETTING -
• Be sure you have a clean air filter, and the throttle
control cable and choke are adjusted properly (see
above).
• With engine off turn idle mixture screw in (clockwise)
closing it finger tight and then turn out (counterclock­
wise) 1-1/4 to 1-1/2 turns.
FINAL SETTING -
• Start engine and allow to warm for five minutes. Make
final adjustments with engine running and shift/ motion
control lever in neutral (N) position.
• With throttle control lever in slow position, hold throttle
lever against idle speed screw and adjust idle speed
screw to obtain 1300 to 1500 RPM.
