Sorry reposting since it posted in the wrong place.
The machine I sew on at work is a Consew 206RB-5. The person who worked on my machine is a traveling repairman who works on the ones at work. (No local repair shop here in Wilmington, NC) Loop happens on left and right turns. Also it is actually the stitch that you stop on that is looping not the next one. I will attempt to make a video soon of the process top and bottom to better help. Stay Tuned !!
Thanks
