Carburetor fine adjustment

Climate change these days obliged me of further adjustment on Solex 34PICT3 carburetor in VW 1302 Super Beetle.
More air supply on idling phase and closing bypass screw obtained more stable and smooth operations including low to middle speed transition, disappearing strong and stimulating smell of exhaust gas also was the result.

Complicated and time-consuming procedures are required to keep the AD 1600cc Boxer motor's condition utmost, still my air-cooled Beetle has enough fascinations to make me feel keep this automobile much longer, at least 10 years more.

On the other hand the passenger's automobile fully controlled by sophisticated electric sensors and semi-conductors has not tendency to be destroyed the stable condition. So no interests are invited in the motor healthy condition, no anxiety has been occurred before Legal Inspections if the automobile was a recent ECU controlled one.

The anxiety because of mechanical carburetor, WEBER 40 DCOM in Talbot PEUGEOT 205 Rallye, raining, snowing and changeable humidity were the reason. Carbon Oxide 4,5% and Hydrocarbon 1200ppm were the almost the limitation for WEBER side draft Racing Carburetor.
