After thinking about it I think if there was a way to measure slider position that would relate really well to fuel flow for everything except wide open/idle. And for that A good guess would probably be close enough.

I don't know if it would be easier to figure out how to measure the slide position and guess, OR retrofit fuel injection
But for fun, lets consider some strategies for measuring the slide position:
1. a "fish finder" type circuit (needs single digit microsecond accuracy at these distances) above the diaphragm to measure its position.
2. a cds/light source sandwiching a window with a tapered shaded area that moves up and down with the slide.
3. a variable inductor in the diaphragm (liking this one best so far)
Any others? I suppose one could test the fuel flow rate at different slide positions on the bench and build a map from there.
