Janome 6600P tension issue
Haven't sewn in a while and finally got the itch to stitch and wouldn't you know there's a problem with my machine. The bobbin thread looks great, however, the top thread is showing the bobbin thread on top and the stitches seem longer, very ugly stitch. I've cleaned, oiled, changed needle, adjusted the tension dial lower and it hasn't changed a bit.
In my research, it was suggested cleaning the tension uptake thingies with dental floss. Tried that, too. Any suggestions would be very much appreciated. TIA
