i fired up my LionChief Chessie unit this weekend and was greeted with smoke issues. I've had for over 1 yr. Worked fine until yesterday. After adding 6 drops and waiting about 10 minutes, I applied power (ZW-L at 18v) and it ran fine, but never produced visible smoke. I blew down the stack...nothing. After running it at a fairly high rage of speed for a few minutes, i stopped it and using the eyedropper supplied by Lionel on VL engines I "sucked out smoke." It was dense and filled the tube. I also noted smoke seeping around the bottom of the boiler. So it appears the smoke unit gets hot and produces smoke, but maybe the fan isn't working? if it is the fan, do I just replace the entire smoke unit or is it easier to just replace the fan or is there some other fix I'm not aware of???
thanks.
