I woke up with an idea.
No mass air flow sensor. No maximite required.
Use a potentiometer that is geared to the throttle with a small
cog belts. Put 5 volts on top of the pot.

Or you can use a leaner pot with a slide throttle.

5 volts wide open zero volts closed.

Then use my one chip $1 555  EFI.

Super low cost super simple TLC 555 based electronic fuel injection.

You can use a low cost Harbor Freight Voltmeter to monitor
the pot voltage.

There is no system EFI or carb that is lower cost.
