Carburetor adjustment

I was prepared for the treatment of Solex 34PICT3 carburator, studied hard I how to adjust and establish the ultimate condition to pass the legal inspection, limited datum are CO 4,5% and HC 1200ppm.

According to my harder experience on WEBER side draft 40 DCOM twin carburator equipped in PEUGEOT Talbot 205 Rallye, adjusting band was very shallow and difficult to find out the sweetest points of idling screw position. But I did it by myself and brought the 205 Rallye to the not private but public legal inspection line to Neyagawa Osaka.

So the same kind of difficulties were supposed before the actual adjustment utilizing special checking device at the factory.

The thickness of idle stopper is 0,40mm, 2plus 1/2 open as the original setting position of volume control screw and the bypass screw is the only controller of odling speed not the throttle valve on 34PICT3 type being different from another former types.

But the first scaling procedure proved that the carburetor setting was correct enough to pass the examinations with rooms.

The fact that no adjusting was required on the Beetle disappointed me not a little, because the carburetor adjusting procedure was cancelled.
