Factory Default - CPI ARAGON Service Manual

CARBURETOR
Position of the retaining clip
Check whether the retaining clip is seated in the
default notch (counted from above) on the jet
needle (see "technical data").
The position of the retaining clip has
influence on the A/F mixture when the
engine is running at middle and upper
load. Usually, a deviation from the above setting
is not required, except for extreme operating
conditions. Before changing the clip position on
the jet needle, all other adjustments and
possible failure sources have to be checked.
Note the different design of the carburetor
covers of the 45 km/h variant and of the
speed-limited
30 km/h and 25 km/h variants; Formula R and
Aragon: 25 km/h). In the case of the latter variants,
the stop collar in the carburetor cover prevents the
slide valve from entirely opening so that not the
full capacity of the A/F mixture can enter the
carburetor.
Assembly
Put the needle jet together with the retaining clip in
the slide valve. Put the plastic stopper and the
spring over the control cable and hook the cable in
the slide valve.
Align the guide slot of the slide valve with the
guide in the carburetor body (comp. photo).
Place the cover onto the carburetor and fasten the
screws. Ensure a sufficient free play of the throttle
control cable by adjusting the setting screw.
Pay attention not to attach the thread
crookedly!
