Need some Noob help here so please go easy on me and explain it like im 5 lol. So I just got my first pin in my house the 2007 spider-man wooo! everything works great with one exception and i cant quite figure it out. The left bumper constantly goes off on its own and registers points. this happens when the ball loads when you take shots you name it, i did some research and looks like its just an adjustment but i dont fully understand it and dont want to mess it up so any help from you fine folks would be greatly appreciated!
