To answer the OP's question, maybe. It sounds like you're describing the old electronic feedback carburetors, which were the last thing before TBI (and frankly not too different in my opinion). It would depend on how stringent the emissions regulations are where you're talking about trying it. Where I live, there aren't any emissions regulations so sure, go for it.

I strongly disagree with anyone saying EFI is simpler than carburetors. Nothing could be further from the facts. EFI - Electronic Fuel Injection - requires fast computers, multiple sensor inputs and fast injector solenoids.

Carburetors rely on physics. Unless you're S.M. Stirling, you're in the clear forever. A high-altitude nuclear strike will cook your EFI while nothing short of a direct lightning bolt (or a solid whack with a big hammer) will disrupt the function of your carburetor. Yes, they fall away from the ideal depending on conditions. For the most part however, as long as YOU can breathe, the car can too. Sure, it takes some sophisticated engineering to make a good carburetor, but I'd like to point out that that was done decades ago by people whose main computing power was slide rules and an experienced eye.

I'm one of those people who really likes having a full-size spare in the vehicle. Carburetors are near and dear to me for their reliable underpinnings. If my carb stops working, I can probably figure it out and fix it with my hands, with tools that grip and turn. If my EFI quits working, my first resource is ordering a new computer. How is THAT taking ownership of one's equipment?

Also: if you're running E85, you can brew your own fuel! That's seriously taking ownership right there.
