For those of you who are having “clunky upper flipper syndrome” where you can’t make the shot ... I have the fix (at least it was the fix for mine).
The flipper was not performing a full “stroke” because it was adjusted wrong underneath. If you look at the first picture, taken with the game off and the flipper “at rest”, you can see the crank-link-assembly (does JJ still call it that?) is not up against the rubber. It’s not allowing for a full stroke of the flipper. On my game it was causing a clunky shot that never made the left ramp.
I loosened the nut, pushed the flipper “out” so it will NOW rest-up against the rubber (second picture, make sure the actual flipper itself rests against the metal guide behind it) ... tighten the nut, and it now allows for a FULL flipper stroke. And now the shot is amazingly SMOOTH as butter.
I hope this helps!
