Stromberg metering needle dimensions

Anyone know where I can find the diameters versus length of needles BIEM ( part number 1325249) and BIAQ ( part number B20217)? Burlen does not provide diameters for Stromberg needles

It’s all listed in the one of the appendices of the Stromberg carburettor manual.

kind regards

B1AQ .0957 to .0544

B1EM is not mentioned in the Haynes Stromberg carburetor manual but B1AQ is
