How will I know if the belt is good or should I just get a new one? It looks good, no cracks but seems to have some 'give' in it. I guess I expected the needle to move when I manually turned the wheel but if the belt isn't tight enough, it wouldn't allow it to move up and down. I'm beginning to feel a little better. It came with the original manual also so it has all the info about oiling/greasing. I should have realized that it was going to need some attention. Stupid me. I have never had an old machine so it's all new to me. I really appreciate the help.
