Quoted from Pin_Crazed:The eject from the moat that is draining down the middle, that is a common problem, mine did it as well. The resolution is to either change the coil to a smaller size or shim the coil plunger so it travels less distance, thus hitting the ball lighter, You can shim it at the coil stop with some double stick foam and that will lighten it up. Mine almost never goes down the middle from the moat eject now.
There is play in that kicker bracket. You can just loosen the screws and slide it all the way back, usually. that worked on mine.
