Hand heel spins freely jamming needle in down position?

My Singer 427 does the same, but in the up position. At first I was resetting the washer every time, which led to it still revving like a maniac 3 washer positions out of 4. Then, one time I rotated the handwheel by hand and, finding that it engaged, moved the needle from up to down as though starting a new stitching line. The sewing machine re-engaged and sewed just fine. Try manually moving the needle from down to up and then touch the foot pedal again?

I took out the only screw I could find, but the wheel does not come off. I see a pin and a notched washer in there and I think that is what you where talking about, but is there anything else that I am missing and should be doing?

Hello Lacey,
All that has happened is the stop motion has moved inside the balance wheel, undo the screw on the stop motion wheel, unscrew the stop motion all the way off, take the three pronged washer off and put it in a different position, you can turn it upside down if you wish, screw the stop motion wheel back on finger tight, tighten up the screw in the stop motion wheel and test, if it still slips take the stop motion wheel off and position the washer a different way.
