Caroline S,
Here's something else we just found out about the Aldon today. If you move the needle position lever it changed the direction some of the stitches point. If you leave it centered they form opposite what the picture is on the control knob.
So there is something to check out on your Universal Super ZZ Mdl AZZ.
Sorry about the delay on the thread widget thread. I just haven't been able to get to them.
I will some day.
Joe
