I got the machine cleaned and oiled, and just need to add some lub in the under the screws underneath the hand-wheel. I contacted a sewing repairman in Montana with my picture and the story of the smell, and he gave me some options. None of them apply to be except perhaps "the motor shorting out." I'm hoping it's not that; if it is I may need to get another motor. But that would be the worst case scenario. For now I am going to continue using it believing it is a dusty lub smell.
