Here is a beautiful cut-away illustration from the Danish website veteranknallertklub.dk. The venturi is 12mm diameter. The curved pipe is about 13mm. The jet and jet holder are a single piece, like the Bing “early Sachs”. The choke cable and plate are the same as Bing “Solo”, with a “carb” end on the choke cable. The screw-on top cap is M18x1.0 thread and M6x0.75 cable elbow/stop, Ø14.5 slide with slot facing the intake (like other early Bings), and jet needle, are interchangeable with Bing “Solo” and Bing “Jawa or early Sachs”.
From the left drawing, sliced vertically front to back, you can see the little pin that locates the throttle slide, near where the choke cable comes in at. Like the other early Bings “Solo” and “Jawa”, the slot in the throttle slide faces the intake, so the throttle slides interchange (but not with “1970’s Sachs” and “Kreidler”).
Puch used this Bing “Allstate” 12mm carburetor on the MS50 (Moped Stahlblech – steel sheet) series from the 1950’s to the 1970’s. In 1969 Puch indroduced the Maxi moped, with an all new carburetor design. That carburetor, called Bing “Puch” or “round Bing” was in use from 1969 to 1986. It is way more familiar to Americans because of the moped buying frenzy in the late 1970’s. In the early 1980’s Puch developed their advanced technology future moped. But sales were down, and something like internal fraud contributed to Puch going out of business after over a century. If they had kept going, we would have an abundance of parts for the Bing “Austro Daimler” carburetor.
