BING jets are stamped with numbers, such as 35, 40 (idle jets) and 110, 115, 120 etc (main jets).
One would expect that these numbers refer to the diameter of the jet bore, however this is not the case.
This is confimed by the company BING in Germany.
A few examples of main jets measured with a wire / jet gauge:
BING 44-051
main jet 130 = gauge 120 (= 1.2 mm)
main jet 125 = gauge 110 (= 1.1 mm)
main jet 120 = gauge 105 (= 1.05 mm)
main jet 110 = gauge 95 (=0.95 mm)
