there are actually 2 different screws, 1 to set the mixture with, and the other to set the idle speed with. you found the mixture screw, the speed screw is the one on the side to the rear as I remember with a spring arround it too. some call this one a throttle stop screw. adjust this one to raise your idle speed, and then adjust your mixture screw for the best idle smothness. once you have raised the speed, you should be able to turn the mixture screw in more and get things where you want them. remember that as the speed screw is turned in (clockwise) the idle speed will increase, if you have a tach. set it at about 750 to 800 rpm, THEN adjust the mixture screw.
