ADJUSTING THE PLAY OF THE THROTTLE
WIRE
IMPORTANT
If you bend the flexible shaft, the amount of play of the
throttle wire changes. Adjust the play while keeping the
flexible shaft almost in the actual working condition.
(1) Flexible shaft
The play of the throttle wire that extends out of the
carburetor with the throttle lever in its original place
should be 1 to 2 mm when lightly pulled by finger. If the
play is too large or small, readjust it as follows.
1. Loosen the lock nut and adjust the throttle wire with
the wire brace so that the amount of play is appropri-
ate. The play becomes larger when the wire brace
is turned clockwise, and becomes smaller when the
wire brace is turned counterclockwise.
2. Tighten the lock nut after adjusting the play, and fix
the wire brace.
