Trying to figure out a smoke problem. Bought the engine used last November and it smoked great for a few days. Added some J-T Mega-Steam, maybe too much, half to 3/4 of the dropper it came with. The engine stopped smoking. Tried resetting the TMCC. I could hear the fan but no smoke would exit the stack. I put the unit on the shelf and figured I would repair it when I had time. Never got to it. Yesterday, my son wanted to see it run around the tree. Run it around the track and it immediately started to smoke again. Smoked great for an hour or two. The next day when we ran the loco again, no smoke. Trying to figure out what the problem might be.
