I just acquired a singer 111w155 waking foot machine. All the parts were there but it would not make a stitch to save my life. I down loaded and read every technical document I could find (most of them in this forum...thanks to all of you that contributed). I think I have the machine timed, but I would not take it to the bank. The needle bar has no marks so I used the 8 stitch setting to adjust to the hook. The timing mark for upper and lower was off by one tooth when the arm was at the highes
