"fuel comes out the orifice that feeds the accelerator pump"
This sounds like it pulls some fuel in, then ejects the fuel out. In other words, it doesn't appear that any of the accel pump circuits are functioning as they should be. The outgoing fuel that goes to the four nozzles is at the top of the float bowl in the bowl gasket area (the #2 bowl gets an oring and check valve for the accel pump circuit).
You have two check valves that you need to clear, they allow fuel to pass one way, and not the other. If that is not what is happening, then it is not functioning correctly.
If your check valves are not working correctly, then chances are your nozzles for each carb are probably clogged too.
You have a fair bit of work to do, take your time and get it right, or it won't work.
