SERVICE AND ADJUSTMENT
HOW TO ADJUST THE SPEED CONTROL LEVER
WARNING: Before you make an inspection, adjust-
ment, or repair to the unit, disconnect the wire to the
spark plug. Remove the wire from the spark plug to
prevent the engine from starting by accident.
If a drive belt becomes worn or after the installation of a new drive
belt, the speed control lever may need an adjustment. When the
speed control lever is moved to the NEUTRAL position, the unit
must come to a complete stop. If the unit does not come to a
complete stop, adjust as follows.
1. Move the speed control lever to the NEUTRAL position.
2. Remove the hair pin from the adjuster nut (see Figure 36).
3. Disconnect the adjuster nut from the hydro actuator arm.
4,
If the unit was slowly moving forward when the speed control
lever was in the NEUTRAL position, then turn the adjuster nut
clockwise (forward) one or two turns. This wilt decrease the
length of the speed control rod.
5,
If the unit was slowly moving rearward when the speed control
lever was in the NEUTRAL position, then turn the adjuster nut
counterclockwise (backward) one or two turns. This wilt in-
crease the length of the speed control rod.

7,
Assemble the adjuster nut to the hydro actuator arm and
secure with the hair pin.
Connect the wire to the spark plug. Start the engine and test
drive the unit. Make sure that the unit will come to a complete
stop when the speed control lever is put in the NEUTRAL posi-
tion.
