The air fuel mixture is controlled throughout the range of operation by various needles, jets, and the throttle slide. Assuming they were put back the way they should have been, there are only two things which might otherwise need adjustment: the jet needle clip setting, and the air pilot screw. The jet needle clip (the jet needle is the "toothpick-like" needle sticking down out of the throttle valve slide) should be in the #2 or #3 position as counted from the top. The pilot screw should be turned one to one-and-a-half turns out from fully, but very lightly seated.
Also, make sure your idle screws - the big ones on the side- are turned in far enough to achieve a decent idle RPM.
