matt: well at the time it wasn't making any foam being pushed into the cup. It will produce skimmate for a while but then it will just stop.

JimD: Is the easiest way just to undo the screw and go in from the top?

Where should this screw be set? I mean how many times should I turn the screw driver when putting the screw back in. I counted 6 rotations when I took it out but I do not know if the guy every adjusted it before me. What is a good refrence point when I put the screw back in?
