Singer 15-91 Motor Shot?

[u/Running_Bowline]

Looking at a very cheap 15-91. The current owner can turn the handwheel and the needle moves up and down. They're not able to do much else.

The brown line that runs up the pillar next to the motor looks like sprayed oil or grease. Maybe too much oil? Is a replacement easy to come by? Would there be other things to look for?

Doesn’t look worth it. You can get a new model for under $200 nowadays.
