having really bad problems here with timing. a long time ago, i changed the needle in this machine for a new one and every since, it has never sown properly. i gave it to someone to try and get it going but they messed up the timing on it! i nealy have it sewing but it gathers up under the foot from the bobbin. any help on timing would be a great help many thanks, kevin. kevinssmith@talktalk.net
