Beautiful!!! I was having the same problem with mine and
I discovered I was threading the needle the wrong way!!!
Try threading the eye from right to left!!! if it works than this is a surprise!!! but it did work for me....
I had mine in the shop here and I got it at an Estate sale for 60.00!!the local quilt shop here works on old singers and he said these are so worth it for sewing on multiple fabrics... r's is a beauty!!! let me kow if this works for you... :thumbup:
