My rocketeer is skipping stitches occasionally and breaking thread as I free motion quilt. I have tried rethreading, cleaning, trying a free standing spool, rethreading the bobbins, different spools of thread, different weights of thread, adjustments on the tension disk and pressure knob and bobbin tension. Earlier today it was stitching along fine for about 20-30 inches then a big wad of thread on the back would stop movement. After going over the steps I mentioned earlier I haven't had that problem just the top thread breaking and unthreading and 3 or 4 skipped stitches in a row.
I am ready to throw the machine out the window.
