Quoted from Marcdaddy:
THANKS for the response in such detail. My MMR played perfectly out of the box and I guess that's pinball if your not tweaking something. Ill try the washer trick first since its the least invasive.
Pinball machines are "Hand Made".
When they are assembled on the line, tiny variations occur in spite of the use of jigs and alignment tools.
Kickout scoops are one of these items that are impossible to get exactly right off the line.
Only through numerous plays does one find out what needs adjustment once the game is settling in on a location.
Since the scoops are set squarely with screws and a drill gun on the line, the installer has only a limited view of how it functions "In-Play".
I havent "Not" had to adjust one in any game I have come across.
Drop target assemblies and stand-up targets can also be adjusted if they are not exactly straight and deflect the ball in an undesired angle.
I see this alot in location games. There will be a stand-up or another target that continually bounces to a "cheap drain" instead of going to the tip of a flipper.
Side drilling the holes on the mounting brackets is the acceptable way of correcting misaligned screws.
There is no easy way to move the screws once they are installed, there is just no room.
