Hi; I'm new to this forum, and I'm seeking help with my Singer 29K60 . The problem is the walking foot moves forward and aft but does not raise up between stitches, therefore it doesn't move the material at all., I've adjusted the the foot tension up and down multiple times to no avail, removed the bell crank and feeding motion ring and checked them for sloppyness (there maybe about 1/32" of play) .Is that too much, it seems pretty tight. I will say that the bell crank is not at a 90 degree angle,maybe about 85 degrees. is it supposed to be that way, could that be part of my problem? Has anyonre else experienced this issue? Is there something I might be missing. Thank you in advance
