186 X2

Can anyone tell me if there is a difference in the X2 throttle body compared with a standard stromberg throttle body, and if there is how do you identify them?

Hi Weddo i just dug out my workshop manual the X2 carb is a BXUV-2  main venturi 1.094"         
similar to the ones used on 149-161 motors but with differences with the idle tube and idle air bleed
the X2 is 70 drill and 52 drill  the 149-161 is idle tube 68 drill ,idle air bleed 53 drill
The single Stromberg for the 179-186 is a BXV-2 main venturi 1.156" hope this helps i copied this information out of an SP Manual that covered red motored holdens from EH to HR
