When you think about it, a carburetor is an amazing piece of engineering. Such a simple technology that utilizes the airflow through it to function. It doesn't require any electrical energy (with an electric choke being the exception) nor a high pressure fuel pump and can provide varying quantities of fuel in a nearly seemless delivery to an ICE from idle to WOT and all points in between.
The engr's at the time used their design and manufacturing techniques to cast the body and drill the minute passages at just the righ positions within the venturi for progressive fuel flow then seal it all up, plus made it serviceable & rebuildable. Their metals and techniques for the most part has stood the test of time, impressive.
Then you look at the timed spark delivery system, i.e. the ignition system. It's so simplistic in operation and yet like the carburetor very precise that it too has stood the test f time.
Basically the engr's take a low DC voltage then convert it to a very high DC voltage (or is it AC voltage?) so as to deliver an arc of electricity into a closed combustion chamber at the exact time it's needed at all rpm of the ICE. Amazing.
They do this by both mechanical and electrical theory.
To go a step further, add a magneto ignition and you don't even need a battery source.....
What we tend to forget is these systems that still work today were devised, designed and manufactured without the assistance of any artificial intelligence, i.e. CAD/CAM or computer generated interfaces, just man using his GOD giving gifts.
I can work on this stuff as it was designed for the avg man to be able to service it.
Granted modern fuel and ignition systems require little service and do last, but when they require maintenance, ohh boy Katey bar the door...... Seems they could have designed a way to read those blasted codes without separate test gear, but I digress...
So I agree w/ HRL and would like to apply these old subsystems on a modern day power plant.
And a redesigned Stovebolt head that's been discussed before.
Anyways, don't mind my waxing poetically, carry on
