Have a Holley 94 carb on my 54 truck 239 ohv that I rebuilt. Truck starts but the fuel and air mixtures screws are not working. I can run them all the way in, and truck still runs when it should die. I know idle should decrease as they are turned in but it doesn't have any effect. Any thoughts? Have tried removing screw and blowing air in holes but no change.

I had the very same issue. When I reassembled the carb I inadvertently placed the float tab on the wrong side of the spring. Other than running a little rich the truck ran fine. I knew that if I couldn't lean it until it stalled there was something wrong. Easy fix.
