SO...put new brushes in the motor, and the motor still has the slows...Guess I need a new motor! Didn't really want to go through this. Don't have time to go through this...whhaaaa.
Something told me to just keep running the machine. I cleaned it, I oiled it, and even tho the new brushes weren't kicking up the speed...I just kept running it. Little by little, I heard the speed increasing!
My blonde conclusion is this...the motor brushes form the end of themselves to the motor shaft or whatever it is they brush up against. They get "concave" to make good contact.
The new brushes were squared off at the end, and maybe not getting enough contact to get good power...but as I ran the machine and ran the machine, they started to form themselves to what they needed to. Miraculously...blonde reasoning or not...I am back up and running!
I was going to pick out the "too big" stitches, but decided to leave them. it represents something significant in my life right now...that sometimes, even if we are slower than we we feel should be, we gotta keep plugging away at it, until we can fly :c)
