Need help. The outhole kicker on my space station has been sticking lately and the ball keeps getting stuck there. During the game, it will eventually look for the ball and jar the ball loose. After the game it prevents the ball from going back into the game and says pinball missing when I turn it off then back on. I looked for any debris and couldn't find anything. Pictures are attached. If anyone could provide advice, I would really appreciate it. Also, I am very light in the pinball repair skills area, so please be as detailed as possible. Thank you very much.
