Suddenly ceased to form stitches, following my change of straight stitching to zig-zag, during the process of sewing a 3 width curtain. Thread became tangled in the bobbin and the needle jammed. Having freed the needle and bobbin and reset machine to straight stitching again (and oiled the shuttle), the same problem remains. Any suggestions for remedying this please? PS Needle is correctly placed, bobbin correctly threaded and machine correctly threaded also.

Hello Liz,
It sounds like you have checked everything so the only thing left could be a timing problem, I can attach timing instructions if you email me but you must type in my address as you say it not as you read it because this site no longer allows email addresses to be shown.
