Quoted from snaroff:Here is an annotated before/after photo that describes what fixed this for me. After a dozen or so launches, it seems to have done the trick! More testing is necessary, but looks good so far...
I decided to take another look at mine. ( plunger is working fine now after the wire form was raised) I have no gap. I did notice that the Plunger to Ball geometry is off and remains so due to the fact that there is no adjustment to correct it. The plunger is centered (left to right) but not vertically. The plunger is actually hitting the top of the ball. Again, there is no adjustment (bending included) to correct this problem. So in summation, launch power on the ball will be decreased due to this condition and there is nothing you can do about it that I can see. My game is launching fine so I am not going to take this any further.
