Good info here but disagree with point #3 in post #92.
The guide holes for the met rods, whether CS or production TQs are not air bleeds.
Air bleeds occur AFTER the fuel has been metered by the main jet.
In the above scenario, the fuel has not passed through the m/jet. The air is atmospheric pressure acting on the fuel above the jet & fuel will flow when the pressure at the discharge point is lower than atmospheric.
