So I have two machines... One of them is new (like 2002) and the other one is old. like 70s prob. on the old one, I have a problem with the fact that when you get it into a hole, the ball goes into the little jackpot area (where the little see-saw with the ball trapped in it is), but IT WONT PUSH IT DOWN. It just stays there. I have tried lubricating it and everything and it just wont go down at all. Not sure why this is. PLEASE HELP! I would love to see it working as my friend gave it to me to fix and that was like a couple years ago. Thanks!
