    What is the correct name for a pilot air screw with a cross drilled
    hole in it?

    These were used on Mikuni VM carburetors 30 years ago...

    AIR, once the screw was turned out about 2.5 ~ 3.0 turns, the cross-
    drilled hole by-passed air and made the mixture as lean as the pilot
    jet would allow...
