I'm having problems with skipped stitches with a 'newer' Singer - I've racked my pea brain trying to figure it out on my own... it only skips when it trying to do zz and only on one side. Makes me think the timing is off slightly. If you can't change it from the gear end maybe you can change the needle bar just a little. Is it centered? Is the needle bar bent just a little? About the only way to tell if one is bent is to pull it out and look at it unless it is obviously bent a lot. I had a 411 give me fits until I pulled out the needle bar and tried rolling it across the table. Once you learn how to put it back it isn't a bad job. The first time I did one I was shaking like a leaf and I had my sister there to observe. Best to make marks - that needle bar is slippery.
