Necchi Supernova freeing up the frozen feed dog piston (plunger) as recommended by Kristin Kay Harmon in the Italian Necchi Sewing Machines and Accessories Group on Facebook. A combination of cleaning with (kerosene or rubbing alcohol), and oiling with Tri Flow oil, gentle tapping, jiggling, and a bit of a warm blow dryer, heat it up enough to free it, then clean it throughly, once free, before oiling, and running it , while raising and lowering the feed dog control, to make sure it is completely functional.
Notice the brown oil on my fingernail as I touch these parts, you can see I haven't quite gotten all of the old brown oil removed (which is what froze it up), when I first made this video. I cleaned more, then made another video, which is also here on Youtube, to show how it should be moving.
