Okay, after a bit of frustration and some time to cool down, I've found two likely culprits in this distributor for a lack of advance.

The weights are dragging on the metal ridges used to support this distributor, as opposed to the nylon bushings the OEM uses.

The springs were also installed upside down from the factory, so they seem to be blocking the weights from providing whatever advance they should be. Seems I installed my light springs the same way the factory did, and it causes the same issue.

Still unsure of the exact cause, but after having a broken clip, and taking a good look at the inside of this thing, I'm still returning it and purchasing something of better quality.
