Quadrajet Accel Pump Issue

[rcazwillis]

Rebuilt a quadrajet. Bowls fill as expected. However, the accelerator pump is not working. Took it apart and filled the pump full. Squirts as expected. Back together, nothing. Seems the fuel is not transferring from the bowl to the pump. How does it pass between the two? Is there perhaps a passage in the bottom of the bowl that is clogged?

I am about to give up and put a holley on it. Shame, I know. But I can tune and make a Holley work.
