Quick carb question.
« on: August 01, 2019, 10:26:05 PM »
On the early ( screw top ) 750 carbs which jet  do the air bleed passages in the carb throat supply . I.e., does the left one go to the main jet and the right one go to the slow jet ? Had a diagram, can't find it .

The one with the brass insert goes to the main jet. The air passage with no brass insert is for the idle/low speed ie pilot jet circuit.

Note that the brass insert is always “towards the centre”. I hope that comes out clearly in the pics.
