Timing An Adler 291

[susiesmooth]

Im wondering if my problem is a safety clutch as since having a minor sewing problem(though there were about 4 rotations worth of thread caught up under the bobbin holder) the hook & needle timing appears to be waaaay out now, about half a rotation away from meeting . I've never heard of a safety clutch. Does anyone know whether an old 291 would have one?

I've split your post off the old thread you tagged onto.  Much better to start a new thread and specific to your machine.
