CW should lean it out.

CCW should richen it.

Unfortunately, it is common to find these tampered with. The adjusting screw is 
covered with epoxy when new, but there are always some people who figure that 
they can "improve" on the factory setting. You can try to readjust it, but I 
doubt if that will be too successful, just because it's pretty sensitive and 
likely to be hard to tell where the right place is once you get close.

I'm in the process of setting up a fixture to recalibrate these. Once that is 
ready I can put them back where they started. In the meantime, feel free to try 
to lean yours out (NEVER go more than a 1/4 turn at a time) or look for a good 
used, untampered one.
