I feel silly asking this cause I'm sure I'm missing something super obvious, but can not figure out how to adjust this darn thing! I can back the screw off that is to the side (silver one in the pic, just to the right of the balance wheel) and can push the arm over but all it does is spring right back over. I searched here and elsewhere online but couldn't find anything specific to this type of regulator. Here is a picture of the watch to see what I'm talking about exactly. Thanks in advance for the help.
