Quoted from C0untDeM0net:ok, yeah I saw that metal bar and on mine there is not a lot of space for movement of it and can see why Herman doesn't move much. Good to know it's tied to the magnet. There is a loose nut that looks like it's connected to the magnet. I didn't touch it as I wasn't sure what it adjusted if anything. My magnet is quite strong and I regularly get both balls stuck and have to wait for the timeout to start multiball. Maybe some kind of adjustment is needed.
If the balls are getting stuck on the magnet, its quite possible your magnet is not flush with the playfield. That is what the large nut on the bottomside of the playfield is for, allows you to adjust the height on the magnet. You want to adjust it so the magnet top is flush with the playfield. Once you do that, the balls will no longer stick on it.
