thats a classic 2 stroke 70cc driven design with forced air cooling.
It's output is between 600 and 900 Watts usually.
And they normally run at 3000 Rpm 

If the secret is buried in the code, where is the code for this alternator?

There is no code for that it's analog.
These types of generators do not use inverter technology there are some that do and they have a circuit board somewhere.
Also some are for welding in stead of AC.

Anyways you noticed the two small magnets on the rotor these generate a small voltage at startup which is known as the "floor voltage"
This is fed back into the coils and as the device speeds up the rotor's electromagnetic winding turns it into a strong electromagnet.
Speeding up it gets stronger and stronger and it also moves over the output windings on the stator so it starts to put out electricity on the socket.
This is all frequency sensetive so it is RPM related and if you do the math it runs at 3000 RPM putting out 50 or 60 Hertz you should be able to figure out how its wound and then u can understand the wiring 

Ususally there is also a 12 volts output to charge up car batteries and if so you will find a graetz bridge rectifier and a cap somewhere.

If they do not run it's usually the spark plug that needs some cleaning.
It's brushless so that cannot be the problem.

Well,

I was asking specifically about the alternator.  The rotor is two poles, and there are 3 phase windings.  These have a set of mathematical properties, which is code.  Number of windings per phase, and then also the winding scheme, more code.  If you look at the design process of the alternator itself, you need a specific size core to support your target wattage, and everything needs to be scaled accordingly, more code...

So, even though its analog, there is still code...

Not digital. I/O

Yes,,,not digfital,,,,I/O.....

The varnish seems to ALWAYS work itself under the needle valve and seat,,,,if it has a different type carb with no needle valve nor bowl,,,then it is always those TINY screens,,,,can you imagine a screen so small that it will allow gasoline to pass but not water?,,Yep,,repaired several.
