Welcome to the Quilting Board!
I did some more fiddling with the Stitch Length Selector this afternoon. There is some kind screw in the center of the dial that sits behind the set screw in the center of the dial. By taking a small screwdriver and turning the center screw I was able to move that pointy end that juts out of the back. It is the pointy thing that engages with the mechanism inside and adjusts the stitch length. The first stitches were six to an inch, nowI am now getting a respectable 10 stitches to an inch and am not going to mess with it any more.
I also had to spend some time adjusting the upper tension. That was a chore because the upper tension dial is not numbered. I also decided that the first bobbin case that I tried was not going to defeat me either. I played with it's tension screw. Voila, both upper and lower tensions are balanced and providing a perfect stitch.
Caroline, it is gunked up inside... I can see it.

Gorgeous! Let us know how she sews!
She is a beauty! I think you did very well.
Did it come with a book? If not, you could find a singer 15 book online, free, and go to town with the oil and grease. It is close enough to be of help, as your machine is configured like a 15. Joe says to use Singer oil and grease, but not the old stuff. Be careful not to oil where it say grease or it won't stay. Grease to grease and oil to oil. You can't go wrong, just done't use too much oil only just enough to lubricate, otherwise it will make a real mess. Good luck.
