In the shop manual they call it a "vacuum port on carburetor" which is located below the idle mixture screw "A". I thought there would be a vacuum reading at idle - the manual mentions it. Instead we got nothing. I didn't think to rev it a bit.

Longbox55 - thanks for the recommendations - swapmeet on Saturday so I know what to look for.
