Isn't the Auxilary Air Valve different from the Auxilary Air Regulator, which I *think* is part number 36?
I had thought that the AAV provides the "clean and reliable" air source during warmup, ending its effect when the car starts. The AAR, as I understand it, is the temp-controlled (via current) item that provides air to the underside of the throttle valve via a rotating disk. It closes as the current warms the internal arm such that it turns the disk and closes the (when cold) open hole.
Forgive any confusion I might add; my US '78 may be different?
