is it the governor spring in this picture

No, with just adjustments/tweaks. Maybe, if you have some technical/electrical know-how...
-No. The only things you can adjust are how much fuel is injected at WOP (wide open pedal) via the Full-load adjusting screw, at what engine speed fuel starts getting cut via shimming/changing the Governor spring, and how fast it drops back down to low idle via removing/replacing/changing the Intermediate spring. So, you can adjust how quick it revs, how much fuel is injected per firing, and when the fuel gets cut/peak power/engine speed, but I don't see how you can set it up so that it'll increase fueling when engine speed automatically drops as dictated by a setpoint via the engine speed control lever/pedal.
-Maybe. If you have something that can move the Full-load screw in and out while driving, and a speed sensor, I think it's possible to build a circuit that will move the Full-load screw in and out in order to keep everything at a set speed. Whether or not this is easier/cheaper than a cruise control setup that just moves the pedal cable according to some speed sensor, I'm not sure.
