His bike works fine if the tank is in the prime position.Maybe I missed it but what about the tank cap itself venting...checked/confirmed operating correctly?

The Syringe should go back even in prime?
Yes, as long as you are attaching the syringe to the vacuum port on the petcock. There should never be any airflow through the vacuum port on the petcock. If it did, then the bike would have a vacuum leak on the #4 cylinder (or which ever cylinder the vacuum petcock is connected to). Regardless of petcock position, there should be no air through the vacuum port. If there is, then something is not sealed properly.

The tech and I figured a dab of super glue on the male end of the daiphragm would hold the seal to it and would pull it open even if it got a little sticky from the gas/ethanol.
Go Figure...
Thanks for all your valuble input.

In other bikes I've seen the port on one fo the actual intake manifolds.
So it can be in one of several places, but you'll need someone who knows specifically on your bike.
