On my POTC, the 30 degree coil (the one near the pop bumpers) does not properly eject the ball out. It fires, but just doesn't get it out, like it doesn't have enough power. There's nothing physical stopping it - it fires properly, just not enough juice to get it out of the socket. Everything else on the machine works perfectly. Ideas here? Anyone ever used a slightly more powerful coil? I've seen this on several POTC machines (my other one was pretty weak too)...
