24.1 Installation of torque spring
set
Install and adjust the torque spring set using the
following procedure:
1. Set the speed control lever to the high-idling speed
position by adjusting the high-speed set bolt.
2. Turn in the torque spring set until engine speed
drops about 50 rpm from high-idling speed.
3. From this position, turn back the torque spring set
by the specified number of turns (N). Lock the
torque spring set at the position with the special
nut.
4. Install the torque spring set sealing cap and make
sure to tighten the cap to prevent loosening.
CAUTION
There are two types of torque spring set: The single
spring type and the double-spring type. Since each
torque spring set has been adjusted precisely in the
manufacturer's factory, do not tamper with the adjust
screw unless it is necessary.
24.2 Assembling the torque spring
set
When the torque spring set has been disassembled or
its component parts have been replaced, reassemble
and adjust the torque spring set using the procedure
mentioned below:
