    I've had a couple locos that would periodically require me to manually spin the motor/flywheels to get it going again and I came to the (fairly certain) conclusion that both were being caused by a bad motor pole. When I was still just doing DC, these locos would run fine once going but, once stopped, they would sometimes not start again without a manual motor nudge. One telltale was the stall would always occur with the motor armatures in a specific position. I mentioned these locos ran fine once going again on DC, but having a bad motor pole seems to wreak havoc with a DCC unit (all kinds of strange speed fluctuations, etc.). All this said, making sure all contacts are clean as suggested above is a good first step.

    In addition to what was said, make sure nothing is binding in the gears.

    Clean the commutator.

    Not going to give up on the motor yet, I will have all weekend to see if I can get it going like it should. Supposed to snow and ice here starting tomorrow(Friday). Not going to get out except to go to work Saturday. If I cant do any thing with it I will take it to my local store and see if he has any suggestions. Worst case have to send it off to Kato. Any way....thanks for the input. Stu
