I recently did a CPR playfield swap for a friend. No matter how I orient the kickout mechanism, the ball hits either the rubber on the right or the metal rail on the left, and goes back into the saucer repeatedly. It’s made me so crazy that I decided to take put his mech in my Rolling Stones, to see if the problem follows the mech. Just wondered if anyone has run into this problem, with or without a CPR playfield.

I’ll follow up with a slow-motion video soon. Here’s a pic of his playfield:

Appreciate the tips! I’m hoping to get back to this Sunday after hosting a big tournament at my house.

Circling back on this. I pulled my friend’s mechanism and compared it to mine. I bent the 2 little prongs that the ball rests on, and the longer arm, until it looked identical to mine. Now it works reliably. Hopefully it’ll be good once it’s installed in his game.

EDIT: the actual problem was that the arm was contacting the leaf switch on the way up, which deflected the arm slightly. I feel dumb.
