I purchased a 6-44023 Pere Marquette Flyerchief Berkshire in May 2021 and just today ran it for the first time. I have a sound problem. Looking for some ideas.
Details:
-Whistle and bell work fine, steam sounds at start and idle/rest are fine.
-Upon accelerating there is no "chuff" just the idle steam sounds.
-The sound switch is on.
-I swapped a known good tender from a Nickle Plate model and same result. So the problem seems to be with the engine (which runs fine by bluetooth or controller, just no speed synchronized chuff).
I am past my warranty period. Any ideas on what the issue could be or fix?
Thanks. Art
