The engine will still start and run with incorrectly set up accelerator pumps. It will still also accelerate, but it will not be as smooth and/or as quick because fuel will still flow through the idle circuit until the main fuel circuit is called to supply fuel through the jets. The accelerator pumps are designed to supply the extra fuel needed when the throttle plates are opened more quickly than what the vacuum signal can draw fuel through the main system.
I do not believe there is anything wrong with the metering blocks. Sort out the mismatched accelerator pump / fuel bowl situation first and then go from there.

After learning more about bowls and pumps, that's what I noticed. The bowls are the original ones, I just changed the check ball out and used umbrellas, which I thought you could do, since they came in gasket kit. I also replaced diaphragms with new ones, new power valve 6.5, needle and seats and all gaskets.
Problem now is I can't find the ball style check valve anywhere, summit has same style bowls, but set up for umbrella valves. So I'm guessing get same style bowls but that will work for umbrella valves.
