Problem with rebuilt carb - Fuel Flow Blocked?

Mistakes can happen, even with professional services. Now I don't feel so bad about some of my silly mistakes.

Got rebuilt carbs back from WiredGeorge carbs. 

No fuel entering bowls. Complete blockage.

Found this.. all three carbs, same issue.

George was/is very receptive and owned the issue, was willing to take them back and service them. But I didn't want to a) pay for additional shipping b) risk them getting lost c) not being available as I'm soon to start a temp gig and will have no time so d) decided to figure it out myself.

This post is NOT a flame on George, so please don't read it that way.
