Opel Rekord Carburetor Calibration

Below is a list of jet combinations for Carter single barrel carburetors used on Opel 1.2, 1.5, 1.7, 2.5, and 2.6 liter pushrod engines as found in the Opel Rekord and Kapitän models from the late 1930s up to the mid 1960s.

I started compiling this information to help me rebuild carburetors for my engines using carburetors that were used on different engines previously and thus required re-jetting.

Please help me to fill in the blanks and to expand this list to include Kapitän engines and earlier Rekord engines by sending me data you may have on this subject.
