@PH1975 posted:Gmorri29 - Well G, care to chime in with your product number to clarify this issue once and for all?
He did It's 6-11201.
He also mentioned it is a used loco bought from a local small dealer.
G, have you checked page 15/16 of the owners manual for messing with the chuff? Maybe a quick reset of that to manual mode may make a difference? If not, sounds like a trip to a shop that can repair.
