I have a Nolting Funquilter and love it. I watched that Jamie Wallen video and screwed up my tension. I had to reset everything. Being that you're having tension problems, why don't you start using prewound bobbins. Buy thread and prewound bobbins together. It might be easier to get your tensions adjusted.
Cathy Adele, use the slider to select the length of your stitch - I usually have mine on the 4th from the right on the Equalizer. Also, on the Equalizer on the right there is a little knob. If it's up, the machine will stitch only when it's in motion. If it's down, the machine will stitch constantly. I only have it down when I warm up the machine.
Hope this helps.
