piper_chuck....you're missing the point. I/we are not advocating running the
engines sloppy rich....I/we never did. I/we are saying that doing so might
waste some fuel and prolong the break-in by not allowing the engine to
reach maximum operating temperature....however, it will not harm the
engine running it very, or sloppy rich.

No one will argue that running the engine at a rich two cycle is not proper.
We are saying that....in fact I/we agree wholeheartedly.... that is a good
procedure. Not one manufacturer has said that running an engine sloppy rich
will hurt it....ever. Not that it matters, but the reference to the OS FAQ's
was in reference to ABN engines.

If that were the case, there would be no such thing as running a ringless control
line engine....they would have all been destroyed "by the reckless operators"....

...."that didn't know what they were doing".

And of course the new ringless four-strokes would be doomed to failure as well.

BTW....I chunked an OS nickel liner. It wasn't because the engine had run too rich.
It wasn't because the engine had been run too lean. It wasn't because the engine
had been run just right....it wasn't because the engine didn't have the right lubrication.
It wasn't because the engine was operated improperly.

It was because the liner plating was defective, and failed.

FBD.
