Initially I thought this was due to worn motor brushes. I replaced the brushes but it did not fix the problem. Stator tested OK with an ohmmeter so I figured it was the armature part #PS3651001. Ordered that next and that fixed the problem. Spent 25 dollars which beats buying a new one. Next time I'm buying a used one from the 60s or 70s when they made them better! One tip - I had a hard time removing the pin that you need to remove the helical gear. Heating it with a heat gun helped a lot, also helped with replacing it after.
