The only tidbits I have is about oiling and the drive wheel. Before you use it, clean it's surface with sewing machine oil and a cotton pad or piece of soft cloth. Then oil every hole that does not have threads. Turn it by hand a bit so the oil can start seeping into all the appropriate places. After sitting that long the rubber on the drive wheel will probably be flat spotted. That will cause the machine to run very rough and noisy, and it will cause one heck of a vibration. There are a couple sources of these drive wheels on the internet so you might be able to find a replacement. You also might be able to move the one on that machine in or out so a smooth place on the rubber contacts the hand wheel. I have a Free too and I remove the drive wheel when the machine is not in use. The motor is not moveable so there's no way to put anything in there to move the drive wheel away from the hand wheel.
