Why Can't Sewette Sew?
I have been struggling with this little black machine foreveh! I get a few stitches and a lot of skipping pulling. This is a machine from deep in the hoard and who knows what Igor did to her before she came to me. She's been cleaned up and oiled but will not sew. I've checked her needle to hook ratio, tried changing out thread, bobbin, needle, a different hook, a different bobbin case..but that's not it. I've adjusted her foot pressure and that didn't help.
Something seems wrong in the tension parts. This is what she has. Any ideas?

I take it she is some kind of a 15 or clone with the tension on the front ? and is there a pin that releases tension on the up ( or is it down ) stroke ? those some times wear or go missing . just a shot in the dark.

is it failing to catch the bobbin thread when it skips stitches ? if so it means the loop is not being formed big enough for the hook to grab... could be a top tension problem, could be thread hanging in the eye of the needle could be a "catch" or bur somewhere in the thread path..... but the root cause is failure of making the loop.... anything that can cause that is a suspect.
And it sounds like you have checked or changed most of those ... pretty much at a loss needle orientation? wear in the needle bar allowing it to "wander" ?

OK I have white thread on top and navy blue in the bobbin. When I look underneath, the white top thread is grabbed by the hook and goes around and over the bobbin-but not always. I see it go around when the stitch is formed but for the skipped stitches I don't see it so I am guessing that means the hook is not grabbing the thread.

that is exactly what it means ... now we have to determine why.... there usually has to be some fabric there. it holds the thread down... while the needle goes up, that is what forms the loop ....some times a slick or thin fabric with an overly large needle and Fine thread can cause problems...
