Gearhead Question: Master Cylinder

Replacing the Master Cylinder on
morgan1's Ford Festiva. Here's a pic:

Now, when I bench bled the Master Cylinder, I got a good vigorous squirt out of the port labeled "A"
However, from port "B" I got nothing, and then later just a trickle.
When I got the trickle I went ahead and hooked it up and proceeded to bleed out the system. LF and RR bled nicely. RF and LR would not bleed-the air comes out-the air goes back it. Also, noteworthy is that after bleeding LF and RR, there was a reduction is reservoir contents, however attempts to bleed RF and LR resulted in no such reduction.
Made a second attempt to bench bleed with similar results as first. There is suction when cylinder is released, but no squirties when it is compressed.
I suspect there may be a blockage or defect that is preventing Brake Fluid from entering the inlet that serves "B" and sustpect I might need to return the part. There are other craftsmanship issues with this part as well, but the inability to bleed port "B" is a showstopper.
Thoughts?

I might mess around with it a little more tomorrow night, but after that I'm going to have to conclude that it's fscked and get a replacement.
