Ok..when I first started on the first set of stitches I began with a new Microtex needle and 50wt thread. Then I did the cleaning, under the throat plate, ran a thin sheet of paper through the tension disks all clear.
I just changed to a topstich needle because I did read that sometimes a heavier needle is better for the thicker layers. New needle and I changed to a 40wt thread. It does feel like the foot or quilt is catching on somehting but I can't feel what. I also unthreaded and rethreaded the top and bobbin again. Still catching.
I tried to duplicate the problem with a test swatch using heavy muslin and the same batting. Stitches still small, so I took off the walking foot and tried with a regular foot. Stitches are perfect now. I took off the sole on the walking foot and reinstalled it. It seems to be working a bit better. I will check the pressure foot setting.
Thanks for the suggestions!
