SU carb set up 444-544

Hi, still having trouble with carbs.Can't stop them from running over rich. I have replaced the jet and needle,(weak needle)fitted a new needle valve to float chamber (the floats don't leak)and set up the correct distance,7/16th on float forks. The Color tune still shows orange through the range and the plugs are sooting up. What else can I look at that might affect the mixture this way?
