With sufficient air leakage from the throttle disc's periphery, the disc must be closed tighter than spec to keep idle speed under control.
This means that the disc position may place both the idle and transition holes on its atmospheric side (rather than split them as intended).
Is the light showing in the photo enough to do that? I don't know.
