Skipping stitches
My long-arm machine started skipping stitches after I oiled it. I changed needles, thread, bobbin, re-threaded the machine, it doesn't seem to be hanging on anything.checked for lint and fuzz and I have even cleaned the wheels on carriage and cleaned track. The skipping seems to happen going to the right side in a loop where there is a seam. My seams are pressed and nothing I can find that should cause this.Do you have any more suggestions.Thank you.
