The vacuum port for the secondary diaphragm is in the wall of the outer secondary venturi on the diaphragm side. If you look closely down the barrel, you'll see a little hole there.

Manually push the diaphragm link to mimick its operation, and then cover the vacuum hole with a finger. When you release the diaphragm, it should hold the link open -- not all the way open, but it should not allow it to close. If the link returns to the closed position, then the diaphragm has a leak.

This is one of those things that is way more difficult to describe that to actually do. Let me know if this doesn't make sense and I'll try to look for some pictures to point at.
