Hi everyone, first time pin owner here. I recently picked up a Bone Busters in decent shape. It has a few issues that are pretty manageable but one is driving me nuts.

The ball lock on the right (moon st) locks as it should, but for some reason the ball will release when the new ball either comes to the shooting Lane or is shot up the ramp. It only happens about a quarter of the time but it completely ruins the game as when one ball drains it kills the play.

The weird thing is it makes the noise it would as if it fired properly. Conversely when the ball goes through the chair up top it gets suck about a quarter of the time, but that's solved with a quick shake. I have more of an idea how to solve that problem but the moon st lock has me stumped.

Thanks in advance for any help!
