What manifold do you have? Sounds like a single plane and the passenger side isn't feeding anything. If it is a 180deg manifold, doesn't make sense. Best way to set those screws is by manifold vacuum. Adjust them for maximum vacuum @ the same port used for distributor advance. If the one screw doesn't affect vacuum at all, that barrel isn't functioning.
