After connecting the inner shaft to the shaft of the main pipe,
try to pull out the flexible shaft by hand to make sure the
flexible shaft does not come off.
■ ADJUSTING THE PLAY OF THE THROTTLE WIRE
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. (SE7)
(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. (SE8)
1. Loosen the lock nut and adjust the throttle wire with
the wire brace so that the amount of play is
appropriate. 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.
