Thanks shoepatcher and Constabulary for the response. I will try some cleaners and see if it will loosen up. when I tilt the machine back and watch the movement as I try and change stitch length, it appears that it is froze up. I don't see rust, but it does seem like there is an oil buildup that is dried on. The 211G157 is hard to find information on,I'll look for info on the 211W157. Thank You guys for the advice.
