Nick!
Tests for vacuum leaks that require the motor to be running often miss critical smaller fissures.
An absolute test is performed while your carburetor is removed:

The manifold flange should be ground to flat, and the carburetor's flange lathe-dressed, as this interface cannot be bubble-tested.
With carb installed, this seam, and the throttle bushings, may be inspected with an un-lit propane torch, although it will suffer the same lack of sensitivity as any other running test.
No vacuum leak is an acceptible leak.
