I finally got my T2 back up and running. The game plays fairly well now, but the one remaining mechanical issue is that the ball frequently plows right through the raised drop target. The drop target behaves fine mechanically. The switch registers fine, and it always pops up and locks into position when appropriate. However, when the ball hits the target it often drops before absorbing the momentum of the ball, so the ball just continues right past it into the VUK.
While this is only mildly annoying during normal gameplay (it just makes the game easier), it does cause a lot of problems with multiball. Getting > 1 ball into the skull lock forces you to drain the remaining ball and wait for the ball search to pop the ball into the gun, and then it gives you a free SJP shot which totally trivializes the game.
As such, I can't really ignore this issue. Does anyone have any suggestions to fix this? I have never had to deal with drop targets before since only one of my other games has them (and they have never malfunctioned).
