Quoted from Doghouse-Studio:
You all gave me some advice a couple years ago. Still having the same problem. EVERY kick out from the elevator on Aerosmith Pro goes straight down the middle. Every time. Sucks! It’s a drag to play and it’s a drag that this is my first brand new pinball machine and I get no help from Stern. Any other ideas would be great. I’ve leveled and leveled again. Should I go my the level on the machine or with the app? With the app, where exactly do it put my phone or does it matter? Everything else on the game works great. It’s just this issue that’s turning this machine into just a piece of cool looking furniture. Thanks guys!
There are a few things you can try.
Take slow motion video of the ball ejecting from the scoop and see if the ball is rolling along the ball guide on the right. If so, you can try bending it to redirect the ball.
You can slightly bend the top of the eject scoop to direct the ball slightly left or right
You can loosen the scoop mounting bolts and tighten them back down while turning the whole mech left or right
