I guess I shoudl try one out it can't hurt. It's wierd that this engine 
will not ping -- see if yours does! I wonder if the knock sensor would 
work on an engine that doesn't make that loud noise.

I wonder if it's worth it, the whole piston is a sharp edge :-) When 
its' up at the top, there's a 1/16" - 1/8" space between the popup crown 
the the cyl walls. That just screams 'dead spot'. Somehow, it works.
