Mechanical carburetors

Setting the automatic choke module at adequate angled position on 34PICT3 carburetor of VW 1302 Super Beetle, AD motor has acquired normal performances with satisfactory. I knew how much the choke system affected even after the engine warm up.

Remembering the similar experience on WEBER side draft 40 DCOM carburetor adjustments on Talbot PEUGEOT 205 Rallye 30 years ago. The idle adjustments were the keys to carry out the task on 4 positions, twin carburetor with 4 throttles independently on 4 cylinders promptly. I did it by myself without any vacuum gauges nor special tools for WEBER to the revel at passing the Legal Inspection for the regular continuous survey line(not private but regular one).

Though any precise descriptions were not found on WEBER side draft carburetors even in the professional field including Web sites, I could find out the way by myself to understand the constructions of 40 DCOM carburetor thoroughly with desperate efforts.

The determination of initial position of idle adjust screws promptly is the key to success and to establish the adjustment on earth, so any numbers of cylinders are available.

Now I realize how much easier on single carburetor system on Beetle's 34PICT3 to do those procedures is with the comparisons.
