I recently received a new in box MTH PS2 ABA set, 20-2483-1, when I run the set at slow speed, lower than 6 Scale MPH, the second A unit drags the rear truck. I know this is the second motor in the engine and the one without the tach and that it likely won't move on its own unless there is load but the issue I'm having is that it won't spin at all at low speed. Once I get above 6 scale MPH it works fine and the motor and the wheels will spin.
Is there a way to free that up so it will spin at lower speed? I have tried to grease the truck and oil axles etc. With the shell off, if I touch the flywheel, I can get the motor / truck to work at low speed, but on its own it won't until I get over 6 Scale MPH.
If not, given the set has 2 A units with double motors and the other (lead) A unit is fine, is there a way to just remove this motor so that the truck just rolls freely?
