I have a Mantua 2-8-2 that is about 12 years old, but has probably fewer than 3 hours on it since its spent most of its life in storage. It has never really run too well, and at this point I constantly have to tap it to get it to go. It is almost impossible to keep it at a realistic, scale speed, since it will stall. Also, it seems to pulsate a little while moving along, as if it is not getting an even flow of power. I have numerous power feeds around the layout, and I have not noticed this problem with my Atlas and Proto2K locos.
Any suggestions? Do you think I need to replace the motor?
