I have both of these games. The same exact thing is happening to both, the coil doesn't have enough power to pop the ball out of the hole. Sometimes it tries to push it out 10 times before it gets the ball out, that is if it actually makes it out before stopping. I've already tried replacing the coil, spring and armature. I finally just added some bondic on the end. This seemed to fix the issue but then with time the bondic fell off. So, I finally did a bondic/superglue solution that seemed to adhere better to the plastic tip. This has fixed the issue, but I would like to know if there is something I'm missing. I know on newer games you can adjust coil strength.
