This may have been posted before so apologies. My right flipper has always had a hair trigger, super super sensitive, but never really a problem. Tonight the right flipper was sticking up so took a look and could see it's because the button is engaging the flipper without pressing the button.
I took out the screw (1) but it meant it wasn't quite sensitive enough now, so put that back and loosened screw (2) which brings the board away from the cabinet just enough to make a difference. The lights on the board light up when the flipper is active so it's easy to dial in/test.
