Yes, a straight stitch. The bottom is either weird straight with no definition of stitches or the whole thing looks fine but is skipping stitches. I pulled out a lot of stitches out because I was testing it on a couple of quilt pieces just in case it was right, so two pieces of quilting fabric.
Changed the needle, reran the bobbin, restacked the tension x 4, rethreaded the machine several times.
I can't see the diagram on the adjusters manual, I was using
http://mysewingmachineobsession.blog...-assembly.html but I had more errors then successes now I'm back to the tfsr page.
I'm just... missing something...
