Well, just to be ornery, here's another suggestion...
My Duetto has a 2L with Webers. 'Course, mine is the earlier (1600) model, which did come with carbs from the factory (and had no engine when I got it). To me, Webers provide a dirt simple solution. Sure Spica is more elegant, sure Bosch EFI is more efficient, but... when properly setup Webers start, idle, and run great. No complicated wiring, no electronics, no high-pressure fuel system, and you wouldn't have to make any irreversible modifications. I do understand the "keep it original" sentiment, but figure that as long as the next owner can easily convert it back to stock, then I've done my duty.
If your '69 has a 1750, then the 2L wouldn't provide much of a displacement increase. And by sticking with the 1750 you'd avoid having to mate the 2L crank to a mechanical clutch, or convert the pedal to hydraulic. So, sticking with the 1750, but Weberizing it, could be another strategy, especially if the Spica pump needs an expensive overhaul.
