I haven't read this thread thoroughly, but my AC/DC premium auto plunge became progressively weaker until a point where perhaps only one in three balls would reach the "trap' at the jukebox, and many would only reach a point halfway up the playfield. Upon inspection, all mounting screws for the plunger assembly were definitely tight. I made two adjustments...... 1) I slightly closed the gap between the two forks which contact the pinball, and 2) I lessened the free play in the lower pivot of the plunge forks by removing the circlip and spreading the U bracket a little. Don't know if just one of the two changed would have sufficed, but every plunge now has the ball reaching the "trap'.... and usually reaching it convincingly hard. I hope this helps. Rob
