A 222 Featherweight will not zig-zag. The 222's were only made for a couple of years, are relatively rare and hard to find and have the free arm option (the metal flat bed pulls off to reveal the open arm). I'd check to see that the bobbin case is there (expensive if not), overall condition (pin scratches, chipped paint, worn off decals, rusty, aluminum break down, smelly?, broken or rubbery wiring (one of the cheaper repairs). Does the machine actually stitch or is it just the light coming on? Often these machines are sold because they won't sew when the problem is the needle is in backwards, thread is caught in the bobbin case, or the little finger on the bobbin case is not in the notch allowing the bobbin case to swing around and not engage. Happy Featherweight buying.
