It should be easily understood why I wrote the first sentence in my original post.

A "Know it all" I am not, I never claimed to be. I do listen, read, participate and learn, unlike many other "Engine experts".

For the past ten years I have participated in F3D Pylon Racing. The engine for this event is only a fully tuned pipe unit. To this end I have reworked my own engines, modified pipes and molded my own propellers. I do have knowledge on the subject.

Fear not, I will never again attempt to dilute peoples ignorance on the subject of engine break in.
