I have been playing some super8 reels from the late 60's and for the most part they play fine, but I have started coming across some stuttering and/or freezing while playing. I checked the holes on the side of the reels and it looks like they are enlarged/stretched. The parts that play fine and simple squares, but these parts are more of a rectangle than square. They're not huge, but if you look at them, you can tell they are not the same shape as the others. Is that what's causing the stuttering/freezing? How can this be fixed, or can it?
Thanks
