bad bushings can do it. and if they are really bad the com could be rubbing on something it shouldn't be. i figure you cleaned the can and hood for the rebuild. did you re-oil the bushings?

easiest way i have found is after the motor is fully together use a syringe to put one drop on the bushings on each end of the can where the armature goes through them. a couple turns of the armature should help pull the oil where is needs to be. its best to use a very thin oil to reduce drag.

if the motor is not used for racing you can use bearings to replace the bushings. and the bearings will last a whole lot longer than bushings will. but if you are using the motor for a "stock" class race then it would make the motor illegal for racing.

there is nothing wrong with vintage at all. out of 14 vehicles i have one that's brushless. everything else is running brushed motors.
