Everyone who replyed to my tension issue Thank you. The stitches are blanced. I have a thread stand that allowed my heavier spools to feed smoothly through the machine. The top tension, take-up lever thumb screw and the screw and lock nut have been lightly adjusted. Needles are good, no burr.
My only concern about my threads is they don't pass thru the spring in the bobbin. Nevertheless the stitched are good.
