Quoted from ABE_FLIPS:From your images I was wondering if the ball can gets stuck a littlebit right at the beginning, since the plastic doesn't touch the kickout metal protector.
But you said it works, so thats great! Also thanks for sharing the file. LOL at the ABE FLIPS letters there hehehe
Even with a much shorter piece with a bigger gap, I didn't see any issue..I think if your ball is riding the wall that early in the lane then you really do need to fix something with the plunger.
