I won't and don't open the throttle plates enough to expose the transition slots, you want the motor to idle on the idle circuits only, not the transition circuits, correct The myth about the transition slots needing to be exposed at idle has been posted on here way to many times I think if you open the throttle plates enough to expose the transition slots I also think that affects the power valve opening at low manifold vacuum
