This an M Class bobbin, but not sure it makes a difference.

I'm having trouble with tension lately. I can't seem to get it to stay equal. Usually I've got front thread on the back regardless of how I adjust the top tension, even when the bobbin tension says it is correct.

I've noticed something on my bobbin. When I load my bobbin into the casing, I always make sure the thread is around the little hook. First picture. [ATTACH=CONFIG]603148[/ATTACH] And that is what I tension my bobbin for, using Jamie Wallen's technique.

If I take my bobbin out halfway for whatever reason, I notice the thread is no longer around the hook but has slipped down as in the second picture, and that gives me a whole different tension. [ATTACH=CONFIG]603149[/ATTACH]

So, which one is right? Is there something wrong with my bobbin case? Or do I just adjust my tension right off the bat for the thread having slipped down out of the hook? Is there a way to fix the hook?

Thanks, Watson
