Andrew, I don't think anyone here was trying to imply you're stupid. Just trying to help.

But, like Roguedog said, if something is binding with the plug removed, then it's most likely either a bent part or a piece of foreign matter (or, a piece of the engine itself) inside the engine.

The only engine of this size that I've had trouble turning over when new was my Tower .61. But, that was due to a very tight "ABC pinch," not compression.

Let us know the diagnosis.
