To use that carb the first question we need to answer is:
Does that solenoid need a PWM signal or a varying-voltage signal to operate as the OEM intended???

If PWM, you'd need a special module to make that work.
If voltage, a simple potentiometer would work.

Either way, you'll need some way to monitor the adjustment vs AF ratio. But I guess if you use the adjustment only on the highway, you could simply lean it out until it starts to misfire.

To make it automatic, a vacuum switch of suitable range could be wired to trigger a relay that energizes the 'noid circuitry. Might not be real smooth when it kicks in/out, though, but a 'car guy' might find that to be useful feedback.
