99K tensioner spring for a numbered black dial???
Is there a difference between the spring needed in the tension dial parts on an older machine just listed as a 99? I have a 99K... I ordered the spring for the numbered dial (I thought) but it seems too small to fit in my machine. I took the old one and put it back in, but it turns without catching in the mechanism., which why I was trying to replace it. I have fiddled with it and the stitch seems fine to me but I'm not really satisfied that it's right, the + and - dial turn when I tighten the tension and doesn't stay fixed like I think it should. Is this all due to the spring not working right??? I can't see anything wrong with the rest of the parts according to the manual and what I have read and reread. Any thoughts from you experts?
