I was hoping someone else would weigh in on this, I'm glad to help, but I don't want to come off as the fountain of all Star knowledge. Anyway, here's what I know.
To adjust the Angle Lever Cam, you bend it in towards the center column, or out away from the center column. Bending it out will increase the travel of the primer slide (make it go in further) Bending it in will decrease the travel of the primer slide. I hate to state the obvious, but the objective is to get the hole in the primer slide to line up exactly with the primer punch when it comes up.
I have only had to make this adjustment once, and it took very little bending to get the desired results, I removed the tool head from the reloader and used a lead mallet to tap on the angle lever cam. I think you might also be able to bend it by slipping a pipe over it (that was my second option if the former didn't work), but remember, you only need to move it a little bit.
The number on the angle lever cam should match the number on the tool head in the recess just to the left of the angle lever cam. Not only should the numbers match, but the font and position of the numbers should match as well. If the number is stamped in the top of the recess, the number on the angle lever cam should be in one of the corners above the retaining screw. If the number is stamped towards the bottom of the recess, the number stamped in the angle lever cam should be below the screw hole. I have seen a couple of tool heads where neither the recess nor the angle lever cam were stamped.
