The screw is for idle speed adjustment ONLY. They tend to be different lengths, so if you have it at one turn and it idles good, leave it there.
The adjuster at the top of the carb is for taking the slack out of the cable. You should adjust it until there is just a tiny bit of free play in the cable housing, then adjust the idle speed screw at the side of the carb.
