Seems to me a bit has been left out such as how to double check your work. An engine can be tuned perfectly yet I don't see where this was mentioned.
I'm not sure what you mean by Double checking. If you are refering to pinching lines or holding nose up to check your settings, my belief is that this is all covered using a Tach to set the engine. After you have experience, you can trade the tach for your hearing and judgment to some extent. That comes from experience.
Also the relation of so called factory settings to your location in the world.
I wasn't aware that O.S. for instance had diffeent starting setting for the U.S and For Austrailia for example? What are you getting at here??
