Perhaps the collective minds here can help me with a problem:
My Aristocraft Pacific 4-6-2 steamer (not having been run in a year) seems only to run smoothly at near or full power. At about 75% power I begin to see some hestitation (jerkyness) that really begins to show itself as I back down about 50% power. Gears are freshly lubed and wheels are clean as is the track. My first thoughts were to cleaning the motor itself.
Q: Any other ideas or thoughts out there?
