Adjust idling speed *
Use the adjusting screw 1 to adjust the basic position of the throttle valve
and, thus, the idle speed.Turning in clockwise direction will increase the
idling speed, turning in counterclockwise direction will reduce the idling
speed. Normal idling speed 1400 - 1500 rpm.

Adjusting the throttle cable *

A play of 3-5 mm must at any time be left in the throttle cables. To check
the play of the throttle cables, first push back the protective cap
throttle twist grip. Now it should be possible to lift the outer sleeve of one
of the two cables 3-5 mm off the adjusting screw
felt. The play of the throttle cables can be adjusted, if necessary, using the
two adjusting screws.
For this purpose, undo counter nut
the desired play is achieved. Then tighten the counter nut and replace the
protective cap.

tor should be drained in order to remove any water that may have penetra-
ted into it. Water in the float chamber leads to engine malfunction.

steps indicated below.
