Quoted from paul_8788:
The ball is not coming out of the subway about 20% of the time on my Premium. If I test by hand, I am getting 0 failures. At this point my only thought is that sometimes the ball is getting air when headed down into the subway and hitting the top of the tunnel entrance, losing some momentum. I am thinking of lowering my pitch about (at 7 degrees right now).
Anyone else run into something similar, have some suggestions?
I had two different issues with my subway ramp, one as mentioned, that it seems some of the time, the ball would not make it out of the subway. I loosened the nut on the bottom of the entrance to the subway and forced the plastic ramp against the right side of the playfield edge, and then tightened the nut while holding the ramp in place, that fixed one issue.
the other issue was after locking 2 balls in storage facility multiball, it would lose the 3rd one when locking, and go into a complete ball search, and finally give up saying "pinball missing", I found the diverter mech sitting in the subway ramp was a bit to high, and wouldnt divert ball number three for some reason so I bent that bracket down towards the ramp a but more and now that issue seems to have been corrected as well. (trust me it was very strange, not sure why locked balls 1 and 2 were fine, just #3)
one other thing to check is level left to right, I did notice along with the diverter issue, the ball would be sitting down there in subway ramp, and just wouldn't drop into the scoop whatchamacallit. LOL
best of luck.
