I have Lionel 6-28656 Pennsylvania 2-8-4 Berkshire Jr #56 and am wondering about the smoke generation feature. When I add smoke fluid, it produces smoke just fine but the smoke does not puff up into the air. The smoke barely clears the stack and settles all around the loco as if the smoke is eminating from a witch's cauldron or something. Is there a little fan that should puff the smoke up and out of the stack? Maybe it's broken or missing altogether? Is there a way to fix or add a fan if it's not there?
Thanks
