I got this machine a couple months ago (some of you may remember), and until now I haven't had any spare time to sit down and really sew with her. Finally, now that I have a bit of time, I find out that I can barely see at all with her. I've re-cleaned and oiled, adjusted the tension (which did allow me to see some patches on denim), but anytime I try a lighter fabric (yes I changed the needle), I get nothing but either bird nesting, or it won't make any stitches at all....just holes where the needle had moved through the fabric. I cleaned out the shuttle well, and I can't find any issues there. When I go back to a heavy material like denim, it will sew, but often seems to bog down at times (only 2 layers), like it's getting stuck, only to quickly take off again like a rocket. I can see denim, but not smoothly like i should be able to. I mean, my first cheapo plastic Black Friday Brother sews better than this Kenmore!
I have also noticed that the needle often strikes the plate, but I can't figure out why? Anyone have suggestions/thoughts? I really loved this machine when I first got her up and running, and now I'm ready to toss her to the curb! Please help!
