Why does carbon build up on the left side of my piston tops and not on the power side?
And, why is the sky blue?

Not on the power side? You mean the bottom. Well....TR6BILL said:

Nope, not running rich.
If you all were to remove the heads to your engines, you would all see carbon buildup on top of the pistons. The Bentley manual even has instructions on how to remove that carbon.
I guess that the power side (carb side) is hotter, that is why you stagger your rings away from that side.

So, you are saying the carbon builds up more on the spark plug side. This would suggest to me there is incomplete combustion upon the spark, but the gas mixture burns more throughly as the flame spreads across the piston.

If it ain't comin' apart, let sleeping dogs lie. One chunk of "coke" down betwixt wall and piston is askin' fer trouble. Stuff the bores with paper towels instead!
If you just HAVE to do something about it, wait 'til it's running again and mist some water into the throats at 3K RPM.

My old man use to spray a mixture of water and diesel oil into the carbs while the engine was running. He claimed it took care of carbon build up. The cloud of smoke was a sight to see. If I were to do that today, I'd be arrested.
He also would run a mixture of motor oil and diesel in the crankcase every third oil change to clean out sludge.
None of this appeared to harm the engines, but I'm not sure I would do any of this, however he learned about engines as a farm boy, and swore by these procedures.
I miss him....

Most mechanics I talk to (ok, they aren't LBC mechanics) say that is pretty much normal, caked carbon on the tops of the piston. Again, refer to the Bentley manual where they talk about removal of such. I don't believe that they would devote a section to this phenomenon knowing the economy of words they are noted for.
