Does this machine have a "cover" for over the feed dogs. I used to have a Golden Touch n Sew from that era and there was a cover that snapped over the feed dog with two little holes in the throat plate. My sister had a Futura and I think it was similar. A couple of years ago for old time sake, I purchased a touch n sew for $20 . . sews great but will NOT do free motion quilting with the feed dogs covered. I tried everything, but the tension is way off without the feed dogs engaged. FYI
