Hi, I have 2 Fusions, and one of them is new...the other I have been running for 3 years. On my new Fusion, I developed a thread problem that I can't seem to correct. When my Fusion is stitching some of the stitches look a little shaky (not in a perfect straight line..one stitch looks to the left and the other is off to the right a bit) and every foot or so one or two of the stitches are loose, like there is a small loop. I need to pull the stitches around to have the thread loop lay flat so its not apparent. I have re-threaded my machine many times, I have cleaned bobbin area and tension disk area. I have even switched out the bobbin case and tried to slow my machine down. I have replaced the needle and made sure the needle is in correctly and moved the needle between 6:30 and 6:00. Checked the tension on the bottom bobbin and on the top. Checked for anything caught, ran a nylon through all the areas to make sure there were no burrs. I am not sure what else to try. Any Suggestions.
