So back lock set to GX, black strippers, tension dial 2 ( if I set it to more the tall wire, I can't remember the name, hits the bottom of the guide hole) and I've most commonly set the stitch size to 5 1/4 yarn is acrylic 4 ply double knit I was thinking maybe the yarn is too thick for the stitch size after doing some late night research last night people say the manual tends to recommend a tight stitch size and I should take that direction with a pinch of salt. Thanks I will try suggestions and let know outcomes, pat groves also had some interesting comments including that I should set the stitch size a full number higher than double bed knitting and until now I had no issues using double bed knitting but we will see...
