Ok so let me get this strait.
"New in box" means that the used engine has been newly placed back in it's box.
Silly me, I thought "New In Box" meant that someone had bought something but
never used it so it's in a un-used condition in it's original box as if it where new.

Next, "never flown or anything."
"Anything" dose not include taking it out of the box,
opening the small item packets, bolting on the muffler, glow plug and carburetor.
Mounting the engine to a test stand and then running it. Loseing parts off the engine
and haveing to replace them.
