Quoted from A_Bord:I see we've been here before. Nice to know I'm not the only one.

I read that link but never tried it. This is why: I have my Big Game set on 7 degree slope which is way beyond what the factory designed. When a ball got hung up, I would have to lift the play field up about 12" to get the ball to roll on out, which is the exact opposite of shimming up the top fork.
But eventually, I did have to back that screw out.
I was having a lot of trouble with the ball hanging up right at the exit point. So, I bent an slight angle in the launch fork at the two black lines you see. It took those bends and backing off both fork screws to get the ball to roll on out. The top screw is so far backed out that it is almost there just for looks. But now the ball exits like it should.
I still don't know why the coil was kicking the ball out so hard.
