Hello fellow board members...
I am having a tension issue with my Singer 15-91. It worked fine when I purchased it at the beginning of this summer from a local gentleman who refurbishes and sells them on Craigslist. It has sat in my sewing area since then and not been fiddled with since transported; and this is my first attempt to sew with it. The top thread is showing on the bottom when it stitches and I get the same results testing both cotton and sweater wool. Changing the upper tension doesn't change a thing no matter what setting it's on (0 through 9). I think I have the thread path correct and have the thread traveling through the needle right to left. Help please with advise
