The plunger that kicks the ball out of the trough and into the way of the plunger is kicking the ball out so hard that it makes a loud pop as the ball hits the side of the plunger lane and really shakes the machine. Is there an adjustment to this mechanism to make it spit the balls out of the trough with a little less force? It hasn't always done this, and I fear damage. The pin is a RBION. Thanks!
