thanks for your input, Tammi. Miriam suggested a rice sock which I did and I don't know if that helped, or the stuck just got tired of drinking solvent. I cleaned up as much of the solvent as I could, and doused it with tri flow which can sit on it til we get home - I think next Tuesday I will pay it some attention. I know it makes a straight stitch. I'm curious to see if the decorative stitches actually work. the video helped a lot to show us what was supposed to move and how. The needle bar works the way you describe and the needle moves from right to left when I move the red lever. So, I am remaining hopeful.
Will keep you all posted on my progress and thanks again to everyone who helped me.
