I have an 8-year-old Viking Huskylock 1001L and it's been running fine until very recently. It doesn't have a lot of hours on it (maybe 100 - I don't have a lot of time anymore to sew). Lately the thread (I only use Maxi-Lock thread and Schmetz needles) has been bunching on the stitch finger each time I begin to serge (the beginning of the fabric). Sometimes it unjams by itself and I can continue to serger, but most times I need to drop my needle settings down to zero, lift the needles and carefully pull the thread from the stitch finger. I've made every other kind of adjustment I can think of, but the serger still wants to bunch up the thread on the stitch finger. I've changed needles (twice), tried various settings for the loopers and needles and the pressure foot, always kept the machine oiled (something my late mother always stressed -- keep your machines well maintained!), and looked at the presser foot under magnification (it looks fine).
Does anyone have any suggestions I might try before I drag it into a local shop for a complete overhaul. I barely use it anymore and am thinking of selling it, but I'd like to make certain it's working better before I do get rid of it. Of course, if I can get it working like it did when it was new, I might consider letting it sit on my sewing room counter until I need it again.
Thanks for any suggestions you might have.
