Quoted from GeminiGuy:- Consistent drain when exiting the Mystery hole:
Good list - super easy to fix this one ^^ - Remove the target in front of the metal ball guide just to the right of the Tatoine scoop, loosen the nuts (under the PF) holding the ball guide in place, slightly bend the ball guide using a crescent wrench to the left at exit. Reassemble and adjust the coil power to land the ball on the left flipper.
I had a weird one on one of my SW games where fast left orbit shots would go SDTM on exit. Filed a very small burr off the exit edge of the metal ball guide on the right side - problem solved.
