Rush LE flipper started sticking up. Found metal filings in the cabinet and the coil stop buttons were loose. I threw a coil stop I had in my parts drawer in and the flipper doesn't go up as far and the flipper drops a bit if hit by a ball with the flipper up. Hopefully getting new parts from Stern.
Are there bad batches of coil stops and plungers? My plungers were mushroomed as well.
