And now I have to eat those words too. I have a 503 I was going to show someone. While I was waiting for the lady to show up I thought I would make up a swatch. So I was sewing merrily away and the thing would quit after a few stitches. New swatch. It did it again. And again. so I took the lid off. Inside was probably dried 3 in 1 oil. There is a pin like thing the needle bar goes back and forth on - it was gunked up and then if you follow that to the rectangle thing and look under it where it goes under the cam (way at the bottom) - that pin thing was gunked up too. Anyway a bit of clean up especially in that area and she runs slick as ever. Nothing like an embarrassing moment is there?
