I recently took delivery of a Signature Elvira. Good game but I've had heaps of issues with the machine. I think I'm down to the last issue which is the ball constantly flying off the left ramp. The trunk lid seems really poorly made and is really loose. I can't seem to find a way to tighten it as when the ball hits it, it comes flying off. I've ordered some plastic to cover the ramp but that's a few weeks out. Any tips on what I can do please?
