ADJUSTING CARBURETOR
The carburetor has been adjusted at the factory. Should
your unit need readjustment due to the changes in alti-
tude or operating conditions, please let your skillful dealer
make the adjustment. A wrong adjustment may cause
damage to your unit.
THROTTLE WIRE PLAY
Throttle wire play should be 1~2 mm. After completely
returning the throttle lever, take the throttle wire at the
carburetor end in your fingers and give a light tug. If the
play is too great or too small, readjust the position of the
wire retaining nut. Loosen the lock nut and turn the wire
retaining nut clockwise (screw in) to increase the play
and counter-clockwise (unscrew) to reduce it. After ad-
justing, please fasten the wire retaining nut by tighten-
ing the lock nut.
