Thanks for the quick response. I'm not sure what you mean by raising the middle foot "by hand", but everything seems very rigid, unless I turn the wheel. Yes, I do have the manual, which can be found here: https://s3.amazonaws.com/a.teamworksales.com/SINGER+SERVICE+MANUALS/211U157A_165A_166A_566A.pdf The only thing I've found in it that looks at all relevant is on p. 25, "ADJUSTMENT OF THE LIFTING ECCENTRIC AND THE LIFT OF THE ALTERNATING PRESSER FEET". If there is anything else in it that I should be looking at, LMK.

I have a Singer 211U166A that I got for free, including table, servo motor, bobbins, and needles. I'm completely new to sewing, and the machine was not working when I got it. Fortunately, a local repair guy got it going, and I was able to sew several things with it--not leather, but some very thick, heavy, multiple layers of cloth (mostly, sailing-related). Yesterday, the bobbin got jammed, and my foot slipped, no doubt putting a lot of pressure on the drive, which resulted in a clunking noise, and a screw that connects to the reverse lever even fell off. I was able to replace the screw, but now the walking foot seems to not be walking. Specifically, the middle part of the walking foot stays pressed down on the fabric the entire cycle, and hence the cloth does not feed. I have posted a short video here: Any suggestions would be greatly appreciated!
