Pat,
I'm with you on this. I would not operate it any further until it was opened for inspection and fix whatever is wrong. Running it as is, I think, would be a bad idea. Most likely leading to damaging something beyond what may currently be easily repairable. If the owner is not comfortable with that, I would suggest returning it for repair.
I did have a very similar new engine with the same problem, making the same type of sound. I found the bracket holding whistle steam smoke unit was bent hitting the drive shaft. Correcting the bracket also corrected the position of the whistle steam that would not only blow out the by the port in the shell, but also out the side of the engine. Cool effect, but not what it was suppose to do. All is now as it should be.
By the way, these mid engine mounted smoke unit brackets are very easily bent if you do not take care attaching the boiler shell. I sometimes will use a tooth pick to help align the smoke units.
Hope it turns out OK.
