This leads me to think that there is a new problem with the drive function, creating a large amount of drag.
That was my thought too. But he says he can't find anything binding in the shop.
What if the original motor's brush advance was set correctly, but the new motors are not?
A quick test: Run the motor on 12v in both direction. Note the speed, and current it draws. If the speed and current are the same, then the brushes are set at NEUTRAL timing. If one direction is faster and draws less current, then the brushes are timed to run in that direction.
How *much* brush advance you need depends on the application. -- Anyone can make the simple complicated.
