Gents,
I have a MTH 30-1393-1 4-8-2 railking loco. I had just replaced the tether because of a broken tach wire. I did notice before this happened that the engine would run smoother in reverse than it does going forward, especially at slow speeds 3-5smph. It seems as the drivers get to a certain point in there revolution the loco pauses ever so slightly and then proceeds. Like I said it doesn't do this in reverse. The problem also gets worse as the consist gets bigger. I have lubed up all the recommended points, and none of my other loco's do this.
Any idea's?
