Mickey2: I reread your comments and a little light bulb went off, the loops are on top-so we have bobbin issues! Yes! the thread was out of the slot, is it possible when I took a brush to the feed dogs and went under the plate could that I bumped the bobbin thread enough to have jump the slot?
I changed to a 90/14 "quilting" needle
Reverse stitches have vastly improved!
What I am seeing now is puckering of the fabric when in reverse only? Is this normal or to be expect?
