Hello, I hope that I have not missed a thread on this topic since I am new to the forum. I have a Keystone 100 and one of the pegs is not turning freely when I have it in forward. This in turn causes too much tension causing the film to jump. The empty spool is turning freely taking up the slack but the spool that has the film is not turning freely. I cannot see a way to lubricate this arm or even access the gears. I'm sure I'm not using the correct terminology, but I want to show some old films to my kids of the grandparents. Please help!
