Hi,
I had a timing hook problem, and I (try to) fix it with the help of a lot of ressources available on the net.
Things seem to be ok ...
When I 'run' the machine by hand, turning really slowly the handle, the bobbin thread is well catched by the rotary hook.
But when I 'run' the machine automatically, meaning pressing "Start", the bobbin thread is not catched. Never.
To much advance for the hook ? Or is it too late ?
Actually, when the needle is about to move up, the point of the hook is hidden by the needle.
FYI : it's a very old AD-820.
I can't get the service manual (where exact timing should be explained) on the Net. If so has it ...
Thks in advance for your help
