I have a 1967 Nishijin that I cleaned up and mounted in a cabinet. During play the balls hang up on top of the spinners and a couple of other areas. At first I thought this was due to the mounting angle of the machine but doesn't appear to be the case (tilting it backwards far enough would fix it but a slight tilt doesn't help).

Is this due to the glass diameter/mounting issues, pins/spinners being pushed in too far, or something else?

My other 1971 Nishijin doesn't have this issue and I wanted to ask for some pointers before I started to tinker with it.

Thanks!
Taylor
