Thanks! It does need a good cleaning because it had been sitting up for YEARS before I got it and I didn't clean it out well before I started using it. I found the manual on Singer's site, I didn't have any tools with the machine so I will have to buy some.
I don't have my heart set on a new one, but I have been trying to find parts for the machine and it seems this model is harder to find parts for...ie walking foot. Or maybe I have been looking in the wrong spot. It is a model 347.
