Hello. Rebuilding some mechs on Wms IJ. The coil in the triple bank target has a lot of play in it. The single does not. On the single... the coil mount (with hole in it) has a tab on the back side that prevents side to side play of coil. The mount on 3 bank does not. Per the manual My current set up is correct. Can anyone verify if that coil should have a lot of movement or if its a manual typo.
