Thanks for the information and the link to the oiling utube Mariam. I just bought a 403A yesterday. It is very dirty/gritty from sitting in a storage unit and the needle bar does not move from the left position regardless of where the needle position switch is set. When the 0 cam is in and the width is set to the maximum setting the needle barely moves and created pretty much a wobbly straight stitch. It came only with the 0 cam, zigzag foot, and the zigzag needle plate. Luckily, I found 6 top hat cams and some slant needle feet in a White cabinet drawer that I bought. I also have a 301 with all of the feet so I should be okay in that department. It was great to see this thread this morning and I'm glad to hear that the 403 is a good machine. I'll be heading down to the "shop" in a bit and start cleaning her up. I think I'll bring down our spare hair dryer too. I'll try to remember to post what I find is the solution to getting this machine's needle bar moving.
