Table of Variable Parts
Variable part Abbreviations Remarks
Choke Tubes K Made in sizes increasing in m/m in some cases by ½ m/m
  • a) Example of marking: 32 - 23
    to read - diameter of emulsion chamber = 32 m/m
                - diameter of choke tube = 23 m/m
    The choak tube firs a carburetor with a 32 m/m bore.
  • b) Example of marking: 35 X 40 - 28
    to read - diameter of emulsion chamber = 40 m/m
                -diameter of choke tube = 28 m/m
    The choke tube fits a carburetor with a bore of either 35 or 40 m/m.
Main Jets Gg Made in sizes increasing by 5/100 and in some cases by 2.5/100
An "0" is places in front of the size marking of this type of main jet Gg.
Examples: 090 - 095 - 0100 - 0102.5 - 0105 - 0107.5 - 0110
G Made in sizes increasing by 5/100 and in some cases by 2.5/100
The size marking of the main jet G (for the older BF types) is combined
with the marking of the emulsion tube which is an integral part of the jet:
Examples: 105 x F - 110 x 51 - 112.5 x 58 - 115 x 56
Air Correction Jets a Made in sizes increasing by 10/100 and in some cases by 5/100
Examples: 195 - 200 - 210 - 220 - 230
Pilot Jets g Made in sizes increasing by 5/100 and in some cases by 2.5/100
Examples: g 45 - g 47.5 - g 50 - g 52.5 - g 55.
Pilot Jets air bleeds u Made in sizes increasing by 1/10
Examples: 1.2 - 1.3 - 1.4 - 1.5
Pump Jets Gp Made in sizes increasing by 5/100
Examples: 40 - 45 - 50 - 55
Economy Jets Gu Made in sizes increasing by 10/100
Examples: 50 - 60 - 70 - 80
Starter Fuel Jets Gs Made in sizes increasing by 10/100 and in some cases by 5/100
Examples: 80 - 90 - 95 - 100 - 105 - 110
Starter Air Jets Ga Made in sizes increasing by 5/10
Examples: 3 - 3.5 - 4 - 4.5 - 5
Emulsion Tubes s Made with a variety of different drillings. To distinguish each
type they are marked with a number.
Nos. 0 - 9 and over 40 = emulsion tubes with a 4 m/m outside diameter.
Nos. 10 - 37 = emulsion tubes with a 2.5 m/m outside diameter.
Injector tubes i For the various types of carburetor these are available in two versions:
  • a) "High" injector with the outlet of the tube level with the air
    correction jet and outside the area of greatest depression.
  • b) "Low" injector with the outlet of the tube above the spraying
    orfices of the main well and in the venturi throat.
Various Injector tubes are available with their calibration marked accordingly
Needle Valve P Available in sizes 1.2 - 1.5 - 2 - 2.5 - 3.
The size marked indicates the zise of the orfice in the needle valve
through which the fuel flows.
The sizes indicated on Gg, G, a, g, Gp, Gu and Gs jets correspond approximately to their diameter
in 1/100 m/m, but these parts are not calibrated by their diameter, but by their flow capacity.
