Quoted from jecase:
As I recall, there are 2 parts to the lower scoop-- the scoop itself and the metal frame for the coil and eject rod. How the ball rests in this mechanism can determine if it is struck straight on or a slight angle hit when the coil fires. Try adjusting this housing in addition to the scoop housing.
this is exactly how I adjusted mine. Now, mine can be dead-bounced down RH flipper over to LH and trapped, or directly trapped by the RH flipper every time.
DON'T DO THIS!!!
