Having trouble with my Iron Maiden Premium Plunger. It's an early run machine and ever since I purchased a few months ago the plunger rarely makes it past the bumper post on the top side of the skill shot right below the upper left flipper. I have better luck on the initial manual shot but even that one seems to get caught up on the post 80% of the time. I've checked the shooter rod tip which seems to hit the ball pretty much dead center. The automatic plunger may be slightly off where the left side may hit the ball slightly before the right. Not sure if it is a week coil however it's all stock and likely has never been replaced. Seems to be a fairly common issue. Any help is appreciated. Thanks in advance.
