I don't know if your aftermarket carburetor has one, but the Ford OEM carbs of the day had an "Economizer" valve. This sensed manifold vacuum to adjust fuel flow. When they worked, they worked fine. But when the diaphragm fails the vacuum hose just sucks raw gas out of the carburetor bowl.
The test to see if it is good is as simple as disconnecting the vacuum hose and checking to see if any gas comes out.
