Installed the Stern Leonardo shooter rod on my LE and when manually plunged all the way back the ball won’t even make it onto the playfield, until it’s auto plunged. The shooter rod tip is back further on this plunger than any of my other games. The rod/spring is the exact same as the one it came stock with, as I even tried swapping them with the same result. It comes with the “red” spring which looks to be the strongest. I thought about shortening the spring by the sword handle to make up some of the gap. I read about “stuffing” the rubber shooter tip add length. Any other thoughts?
