Figure B–37. Remove Wire Clip & Throttle Cable
From Throttle Lever
THROTTLE LEVER TENSION (MULTI-PART LEVER
ASSEMBLY UNITS ONLY)
Note: Later models use a “one piece” non-adjustable
throttle control that is replaced as an assemble.
1. See Figure 36. Increase Tension - Tighten the lock-
nut (I) by turning clockwise.
2. Decrease Tension - Loosen the locknut (I) by turning
counterclockwise.
NOTE: When properly adjusted, the throttle lever will
allow positioning with light force, and will maintain the se-
lected position without slippage while the unit is being
operated.
MULTI-PIECE THROTTLE LEVER ASSEMBLY REPAIR
1. Remove the wire clip securing the throttle cable (N,
Figure B–36) to the throttle lever by removing the
truss head screw and nut assembly (B & M, Figure
B–36)
2. Disengage the throttle cable from the throttle lever,
and loosely reinstall the screw and nut on the clip to
avoid loss during service (Figure B–37).
3. Remove the throttle lever from the throttle mounting
bracket by unscrewing the hex locknut (I, Figure
B–35) from the carriage bolt (C, Figure B–37). (Keep
the head of the carriage bolt against the throttle lever
to keep the bolt from turning while the locknut is
being removed.)
4. Slide the carriage bolt and throttle lever out of the
throttle lever mounting bracket, catching the spring
and washers as the carriage bolt is removed from the
assembly.
5. Check the throttle lever mounting bracket (G, Figure
B–36) for wear or damage, and remove and replace
if necessary by unscrewing the three plastite screws
securing the bracket to the underside of the dash-
board.
6. Reassemble parts in reverse order of disassembly,
using care to position nylon washers on both sides of
the throttle lever mounting bracket, and the metal
washers on both sides of the spring, as shown in
Figure B–36.
7. Adjust spring tension to provide secure positioning of
lever while allowing smooth operation of lever.
ONE-PIECE THROTTLE LEVER REPAIR
1. Remove the throttle knob by pulling it straight off.
2. See Figure 36. Unscrew the plastite screws (P) se-
curing the one-piece throttle assembly (Q) to the un-
derside of the dashboard, and remove the one-piece
throttle/cable assembly.
3. Inspect the assembly for wear or damage and re-
place as required. (Consult engine manufacturer's
manual for throttle cable connection to engine throttle
linkage, if necessary.)
4. Reassemble in reverse order of disassembly.
