For those unfamiliar with the layout, my Special Force (Bally 6803) has a drop target bank with three targets that are in-line instead of side-to-side like a typical target bank. The targets block the lane and all three must be knocked down to access the lane's primary target (similar to Centaur). Everything works fine except when the ball hits one of the targets too hard it bounces off the target with such force so fast that the target doesn't drop. If the ball rolls slower and hits the target then the targets drop normally.
Has anyone had this issue or know a fix? The targets seem to drop passively with no resistance when I manually drop them with my finger and the "fire rocket" button automatically drops the target just fine. Is there a way to tighten the spring or is there a particular adjustment to correct this on this style drop target mechanism?
