Pete,
Naaaa, I just beat on it! I use it as "the sacrificial loco" to see if the track works right. It's running much slower than it used to. I'm certain it has pulled all manner of crap up inside with those "all wheel drive" gears hanging out the bottom! Remember, this is the one I wanted to enter in the "loco races". Maybe I'll get a chance to pop it open this afternoon and see what all is in there.
Any tips? All I have is a small bottle of Bachmann "Gear Oil", with a little needle applicator, that I bought when I tried to make my Dash run better. (What a piece! I sent it back to Bachmann, but it still runs like sh*t!)
If you're there get back to me and I can swing buy the LHS, on the way home, to pick up any PM supplies you suggest.
Marc
