Hey guys, having a problem with Twister ball trough. The issue is, after a recent complete shop job, the balls are not advancing in the ball trough enough to be picked up. When a ball drains, the inertia isn't enough to push the balls forward in the trough so the balls are between the switches and not being sensed for the coil to fire and advance the next ball.
The shop job included a complete playfield teardown, new rubber, new balls, new LEDs, and a thorough cleaning. The trough was not jacked with however.
I've tried adjusting the switches a little, and lubricating the sides of the trough where the balls rub against them. No luck though. Any chance at all, the pinballs are mis-sized by a couple thousandths? Any other things to try?
