@Gmorri29 posted:I probably should have mentioned this originally as well, but the smoke unit also seems to have some issues. It works, however it does not puff in line with the chuffing. It seems that it only puffs about twice per revolution when it obviously should be 4. It’s also not consistent. When the engine is running, the smoke frequently stops coming out of the stack and starts leaking out from under the boiler as well as underneath the cab. After a minute or so of this, it will start coming out of the stack again, and the process repeats. I’m not sure if this is related to the chuffing issue or not.
This is exactly what my ten wheeler was doing. The chuff switch drives both the sounds and puffing in this engine and if it doesn't work correctly both systems will go haywire. My fix for it was the replacement of the chuff switch assembly, but if that isn't something you can do or want to do then your best bet is to take it to a service center and have them take a look at it.
