WOOHOO!! Thanks so much for the offer!! :)
I have a Kenmore that the feeddogs don't work properly on...they move and "cycle", but they don't drop below the plate, so that all they do is move the fabric back and forth with no progression. I've downloaded a service manual for it, torn into it, and checked for a lint buildup under the dogs...nothing. I've adjusted the height of the dogs to it's lowest point...nothing.
Any other suggestions? It was my mom's machine, I'd love to be able to use it!
