I had the same thing happen on a 14j334 serger, and the only place I could find one was on, but I don't see your machine listed. Try calling them or Singer at 1-800-4singer and they may be able to advise you as to what size it is.

20u73 singer timing issues

is the needle the right one for the fabric being sewed?
is the needle turned the right way in the needle holder and pushed
all the way up in the needle holder?
if the above is totally correct, the I suggest taking the machine
to some other repair person, cause if the repair technican can't
time the machine they should have told you they couldn't work on the
machine .

Hand wheel rotates but stop motion screw doesn't rotate and it is not moving the needle up or down

Robin. Take off the hand wheel. Look for the funny looking washer with ears. The center fingers should be angled outward when you fit it into place (counter intuitive, I know) Fit everything back together and try it again.

Needle hits?

OK, this is a general timing procedure. Loosen the screws on the main shaft gear that goes to the hook drive gear and separate the gears. Next put the needle in the left position and bring the needle all the way down by turning the handwheel. As the needle comes up make the point of the hook enter the scarf of the needle (just above the needle eye)and hold it there while you put the gears back togeather and tighten the screws. This should put it close to being in time. To fine tune it you can loosen the needle bar screw (half way up the bar that holds the needle) and adjust theneedle so the hooks point is just above the needle eye. You may have to do this a few times in order to stop it from skipping stitches. Good luck. Rick
