If it IS correct, you're right...that makes no sense whatsoever since the feed dogs control that length too!

Oh yeah, another thing...At 0 my machine WAS correct before adjusting. It was the other #s that were wrong. But adjusting the eccentric fixed it all. In my case, my straight stitches were too long...4 stitches rather than 6 at the longest length but I could still get a nice zigzag & satin stitch...I just never actually counted the stitches on those! I could also get the straight stitch length I wanted...they just didn't correspond to the #s on the dial. That was driving me crazy....I'm absolutely anal about stuff like that!!!

I really paid no attention to my zigzag stitch when I did this...& it also works perfect. I'm primarily a garment sewer & really picky about straight stitch length for top stitching etc.

If you can locate the "adjuster", I'd try it. You can always mark it's position before you move it...& move it back if it doesn't help.
