So I've noticed the auto plunge on my Star Trek pro has been getting weaker and weaker to the point where the balls are not even getting to the pops.
I pulled the assembly, checked the spring, lubricated the linkages, and...no change.
So on a whim I pulled the balls and wiped them down and then did a good Novus 1 on the playfield and shooter lane. Especially the shooter lane.
Problem...solved? Really?
I'm a newb and ST is my first pin, but does a dirty playfield and shooter lane really slow the auto plunge that much?
