No response from the screws means you are on the main circuit..or there is some kind of leak pulling fuel. If it was running ok but rich I would say you had the speed screw turned in too far exposing the transfer slot..but since you had it apart and it won't idle I'd take it back apart.
Thats what I was trying to tell him. On the Holley I had it didnt matter what you were doing with the idle screws it was still running rich and thats when it was noticed that the rear the secondaries were just pissing fuel down the carb. I think I just couldnt explain it good enough. Thats for explaining it better than I did.
