Yeah, I think I see what you are talking about but now I am more confused. I thought the "squish" are was on one side and that is what caused the piston to rock on the wrist pin when contact was made. These pics look like there are 4 equally spaced. Wouldn't the piston then hit them dead on (all 4 at once), not causing any rocking?

bbobynski, Besides WOT's which clears out the carbon built up, has any other method ever been considered? Is there a substance that when squirted into the cylinder and left to sit would dissolve carbon buildup? I can envision a spray head that you would stick into the spark plug hole that would have the ability to spray upward toward the valve and squish area, and of course the top of the piston also.

Let it sit, start the engine and change the oil. Could anything like this ever developed or wouldn't this work? Thanks, Mike

Early on sailors navigated by the stars at night and the North star became the symbol for finding ones way home. Once you know where the Northstar is you can point your ship in the right direction to get home. So the star became a symbol for finding ones way home or more symbolically even finding ones path in life.
