Motor for electric leaf blower

My leaf blower stopped working.



I tested the switch and it was fine.



Power is getting to the motor.



There was a black buildup on the armature, so I sanded it with a 1500 grit sandpaper.



Now the motor starts but it stumbles.



Is there anything else I can do or is the motor toast?



Thanks,

Andy

Hi there, looks like motor has commutator and brushes from your reply (assume universal series wound motor). Commutator segments may need undercuttingas was common with automotive dynamo's. The Haynes Automotive Electrical systems service manual mentions an undercutting tool and in the starter motor chapter, a
growler tool is mentioned which checks the armature winding insulation by electromaganetic induction.
