I recently added 10-12 protosmoke drops in my MTH NY Central PS3 Steam engine. When the engine runs smoke comes out from the sides as well as the stack. It looks kind of cool as if smoke was coming from the side pistons but the train didn't do that at first and I don't believe that suppose to happen. I don't think that I put too many drops in. Any advice on how to correct this? Will it eventually burn out or does it need service? Any input is appreciated! Thanks!
