Picked up a nice AC/DC prem and the band mech isnt firing properly. It fires, but at times it doesn't come back. I have tried filing the plunger and the stop, helped a bit. I then put a little chunk of super band between the plunger and stop to see if it was a plunger/stop contact issue and it is, but the superband limits the movement of the band members.
I would buy a new mech, but can't find on Marco or pinball life. Any idea's how I can get it working?
