I also have dreamed about adjustable fuel jet.
I have placed an cut-off solenoid in my idle circuit and also put a switch in the dashboard to shutdown the idle circuit on highways.
Idle circuit is only partly involving at higher speeds, so cutting off the idle will lean the mixture a little. So I might say i'm half-way there

Then I build an pulse width controller to adjust the idle circuit open time at lower speeds, but sadly I haven't tested it yet.

An oxygen sensor in the exhaust will help seeing whether its lean or rich. And the other thing is the feedback what comes from pressing gas pedal. If not much power then it's propably lean.
