This will depend on your personality but I prefer to spend money on a reference that will last me a lifetime rather than a repair that if done right will last me 6 months. Besides, most won't get into motor stuff, other than changing the brushes.
It's sort of that "give a man a fish feed him for a day, teach him to fish and he'll sit in a boat and drink beer all day." No wait. That's not it....

What I found out was that the commutator, brushes and their tubes was contaminated with oil. I carefully removed the brushes and cleaned them and the springs and caps with denatured alcohol, then used a q-tip with the alcohol to clean the commutator and brush tubes.
End of problem the machine works fine now.

Do it growl when you step on the pedal or do nothing at all? It's possible too that the pedal needs adjustment. I hope it's not the motor, they're a little finicky to deal with on the FW because the wires are so short and the motor casing is a little more challenging. Not un-doable, just a little more of a pain
I would also make sure that the belt isn't too tight. How's the temperature of the motor once it's been running a while?
