Stop stop your both correct!!!!!
The issue is getting a computer system to feed the stochiometric (ideal)14:1 air to fuel ratio to the engine under warm run conditions, variable loads, and speeds ranging from 450 to 2500 (for those with the wick turned up higher).
Also needed is a method of providing cold start enrichment, and high vacuum shutoff.
The best approach is to use a system that triggers off of a crank sensor (magnet can be placed on flywheel), oxygen sensor (drilled into exhaust manafold), and various temperature, pressure, and air flow transducers. I think it is entirely possible. Robbing a donor car, and making the system work correctly is not hard, just time consuming and worthit if the end result is good looking, functional/reliable. It should then be written up in a how to booklet so that others can follow by cook book implementation.
Govenor action would be from existing linkage to the throttle body, or air flow control. Would it help? yes.
We could even use a catylitic converter to advantage.
For antiques and show purposes, no way.
Our future with working tractors is to be responsible, conservative with resources, and to not throwaway good usable high reliability hardware. the prices of new tractors wounds my retinas.
It is an item I hope to "supercharge" some of my better students into attempting in the next few years.
