from personaly experience, tightening the idle makes it lower, and vice versa, it only worked for me when i disconnected the battery and tweaked the screw then, otherwise it didnt do anything. as for running rich, what signs tell you that? try reseting your ecu so it can "tune" itself to your conditions
