Fuel Mixture Not sure if running too lean, or too rich, or perfect?

Plugs do not come with any recommended ambient temperature to run at. I recommend the number 7 plug.
Running too rich will let the engine run cooler but you will break down more often with a fouled plug. Put a leaner main jet in.

I run 20# head torque on 66cc engines.

Yep, X pattern 5# at a time with a torque wrench, that means 3 X cycles.
NOTE! I ONLY buy real Skyhawk engines, they don't skimp on quality and at 20# I never have head problems.
Cheap ass engines may have different results.
The point here is not how tight you can get it, its how you do it, and you can't do right without a torque wrench.
Then just take all 4 nuts down a little at a time in an X pattern.
