New to the air hockey scene and just picked up an older MD Sports 7 foot table (2103 Model). Upon turning on the table, the entire center of the play surface lifts up a good inch or two, so the play surface is not even. First question, what would cause this? And secondly, any recommendations on how to repair it? I've read that the air holes may be plugged, but I used a large sewing needle to unplug any holes that appeared to be plugged. I can feel decent air flow over most of the table. Is this an adhesive issue with the surface? Something else? Does the surface need to be replaced and if so, any recommendations on where to purchase replacement play surfaces?
Any ideas or suggestions would be greatly appreciated! Thanks!
