Well, used all your suggestions & got it working. I had to adjust the timing and got it sewing after using a lot of thread. I used up a whole bobbin fiddling with the hook that when I reached for the next bobbin and then it wouldn't sew again....
So I held the bobbins side by side and there was a slight difference! Sews a beautiful SS.
The bobbin closest to the needle is the one which works - less holes? I wonder if this kind has a number?
