The "A" and lightning bolt drop targets have some serious issues on my left bank of drops. The "A" target has a hard time holding when being plunged up. The solenoid will often fire 2-3 times before the target sits and sometimes it will fire five times and then just give up, leaving the "A" in the down position.

The lightning bolt target, on the other hand, has a hard time dropping. One outta five times, I will dead on hit that target with the cannon and it will just stay standing.

I've had these problems on older 80's pins, and usually it's an easy fix like re-positioning the entire drop target mechanism. Unfortunately, on this pin, the position the mechanism is currently in looks perfect as all targets are pretty much flush against the center facing portion of the pf.

Any ideas?
