That's an odd situation. Are you sure that you don't have a leak at one of the carburetor body gaskets or perhaps a manifold gasket?
I believe that carburetor should have a thick heat insulator/spacer between it and the manifold. It doesn't appear to have one. Lack of the spacer can allow the carburetor to get too hot, which can affect the fuel mixture, especially at idle and low speeds.
If the idle mixture screw is actually turning, putting a small washer or two or three under the spring should stop it. It may be the wrong spring for the application.
