Success! Thanks to all of you. TrainLarry will be happy to know I took most of it apart--cleaned all I could as best as I could, was able to put it back together without any parts being left over, and it's running like a top.
In the process I even fixed the smoke unit ( the "activation" bar was not place in it properly and just needed to be put back "in the groves") --now it works too.
Thanks to all of you. Yes, I use to do this kind of stuff long ago as a young teen in the early 1950's --but time and technology have kind of passed me by.
My next project is to get the DU side (lever) to "zero out" on my ZW transformer (275 Watt) --purchased in the early 1950's. But that project will have to wait for another day.
