I am having trouble getting the tension right on my machine. It looks to me like I need to adjust the bottom to pull the knot through to the middle. Still working on that. Second problem is this puckering on the bottom side hole. What causes this? Is this the needle sharpness? Tension?
I just received the two new tension screws for the bobbin shuttle (small one I lost and the big one was starting to strip so I ordered both) from LMC for my class 4. Where do I start once I change the screw(s)? Try the middle and see? Any help would be greatly appreciated.
I included a photo that shows both topside and bottom with the puckering. Thanks.
btw this was two layers of 5-6
