d) Insert the governor lever into the governor shaft.
e) Insert a minus screwdriver into the groove of the governor shaft, and turn the screwdriver fully in the
clockwise direction, Push the governor lever clockwise (at this time, the throttle valve is fully opened)
and fasten the governor lever with the lock bolt.

center hole (of the three) of the governor lever and the remaining end inserted into the hole of the speed
