I have an early run AMH, this happened to me. No matter what I did, I couldn't get the scoop to kick out correctly. Then I noticed there were some broken welds on the scoop. Called Spooky, they shipped me a new one, I had to pay for it. The old one had two welds near the speration, the new one had 4 or 6 where it separated, but the scoop they sent me was reinforced greatly.
Now the ball goes to the right flipper 9 times out of 10.
Quoted from TomGWI:What do you guys have your scoop set at in coil settings? Mine is at zero now but I had it at 2. I either get the ball SDTM or bouncing off the slingshot post or on the right flipper. It is pretty random.
