Hello fellow members, Has anybody encountered problems with the steam to the cylinders. The locomotive has been totally stripped and all ports cleaned with copper wire and air-dusted. New seals fitted to steam chest and cylinders. Re-timed with new electrical connections. At the moment I have changed over the SUPER HEATER with another that worked on my other locomotive. The steam appears to build up as the whistle sounds but NO steam to chest or cylinders, is it possible that the super heater element is slightly under par and not giving full heat. Or is there a extra steam port in the oil intake chest that you can not access any advise would be most appreciated cheers!!!!!!!!!!!!!!!!!!! steve.
