If you are running a little lean, then one click clockwise (right to richen, left to lean) should do it. You can do it while you're running at idle....just do not press down too hard. Very slight pressure down while you're rotating the allen to get it to slip into the socket.
Has this car been running lean since you had the car? Have you made any changes to the engine? Generally, this is a set once, forget about it adjustment. Header, cams, turbo changes, for instance, require adjustments. I always recommend checking hot and cold control pressures before touching that allen.
