The website was a great help but there was only one little piece of thread found and removed. We got it back together but there was no improvement. The machine will only make 1/2 - 3/4 rotation of flywheel.we tried oiling and greasing hoping things would loosen after it soaked in, but to no avail. Luckily the seller is willing to refund $$. We are mailing it back tomorrow. It was a short bed anyway and I prefer the longer ones. Sure am curious as to what the problem is though. Just not curious enough to spend big bucks at a repair shop. We want to learn to do these things for ourselves. Any suggestions on how to learn more complicated repairs would be appreciated.
