Quoted from jjga:The one thing I need to sit down and tune on mine is the kick out hole mechanisms. On mine, sometimes one visor hole launches the ball straight down the middle, and the other two drop it right in between the end of the flipper and the SDTM post, which makes the game unplayable.
Check the kickout end hasn't mushroomed... or is bent, thats the biggest culprit of SDTM from either eye socket or left saucer, also check if there is any slop in the kickout bushing. The next culprit is usually week kickout coil which could be power supply low voltage related, or a bad coil. If you own a Pinbot in HUO, its worth replacing the kickout arms once and then you can pretty much forget about them ever wearing out again.
