I fiddled with an Electro Grand Japanese badged with cams (cams missing) Some of it is not intuitive. There is a zig zag dial on the front either doesn't work right or I am missing something. I'm sure someone here will know. The machine was not turning. I started oiling and came to the nose area - there was thread wrapped around the some of the moving parts or not so moving parts. I got the thread and a ton of lint out and the machine turns nice. Then it was missing the bobbin case and the needle clamp so I dug through parts and fixed that. I set the tensions and the machine stitches a nice stitch. I also had to free up the feed dog drop & buttons. Now I need to figure out how the cams and zz work. What is B - A - M ??? it has to do with the cams but nothing stands out at me on this machine. The zz dial side levers seem to be a bit gooey inside, too. There is a cam in there but the stitch did not resemble the cam at all. The cam is seated as far as that goes.
