Got a 301 from eBay. But it seems to be frozen. We can't even turn the wheel by hand. We have cleaned, oiled and greased everything but it hasn't helped. We can't figure out where it is seizing up. We are thinking of sending it back if we can't figure out the problem. Don't want to spend a lot of $$$ on repairs as we are thinking of having a booth at a quilt show next year and doing some selling. Anyone have any thoughts or suggestions? DH is enjoying cleaning these up and doing repairs.
