THROTTLE CABLE ADJUSTMENT
The throttle cable can be adjusted using the screw set on the
throttle, or using the adjusting screw set on the
carburettor cover. To check for proper adjustment of throttle
cable, proceed as follows:
- remove rubber cap;
- move transmission sheath to and fro to ensure a play of ap-
prox. 1 mm;
- should play be greater than 1 mm, loosen lock nut (1) and
register (2); should play less than 1 mm, then tighten lock
nut and register;
- if register (2) should not provide sufficient movement to allow
for correct adjustment, then adjust register placed on carbu-
retor.
There should be approx. 1 mm play on latter register; should
this not be the case, then loosen lock nut (3), and loosen or
tighten screw (4), to respectively increase or decrease the
play.
