Hello,
I have a Who Dunnit? and the right reel on the slot machine. Seems slow and does not stop at the intended picture. I think the reel needs to be re-adjusted or tightened on the motor arm? I did do a test in the menu and the opto is working and the reel does spin. It just seems that the right reel is slower. Any help or advice would be greatly appreciated on how I can tighten the right reel so it spins correctly with the motor arm.
