Unsure, but I do know I put in a wavy washer and cinched this up, but it didnt alleaviate all my SDTM completely. I ended up twisting my scoop towards the left flipper by about a degree to a degree and a half, pointed it so full power kick out was aimed (mostly) towards the flipper bat/shaft axis, so under powered kickouts puts it on the tip, and over power kickouts will send it up the left inlane. Problem solved. I made MOR again yesterday, finally kicked the default MOR 200mil high score champion off the board with 220mil, but missed my GC score of 543mil+ with a measly 524mil. I am set at factory freeplay with the exception of minimum 8 sec ball saver and tightened outlanes. My Replay and Special awards are set to award extra ball ball. So your average game ends up being either a 4 to 7 or 8 ball game, however depending on if you get your replay, and scoop awarded extra balls. If you have not got to MOR yet on your MB after playing it 3 months, its time to finally turn on the ball saver and tighten up your outlanes, imho. MB was brutal on site back in the 90’s, most ops that ran one ended up with the ball saver on after the first two weeks. Casual earnings recovered after that but any machine at one of our old pinball haunts at the time kept the outlanes open and the ball saver off just to keep earnings up since we were getting real good and our ball times skyrocketed. Right now my game time average is just 4min and 20 seconds, so my setup isnt as brutal as it could be. And my outlanes, although tight as they can get, are still ball hungry bastards on this table.
