i have no idea how its controlled, ive thought about picking it up just to figure it out, but i dont have that kind of money.

 

naft hmm no easy way to explain it but its basically nozzles with certian size jets in each cyl,that continously spray fuel, though there are various ways of controlling the amount of fuel and preasure to the nozzles with the throttle,by either engine driven fp, or a system of throttle actuated valves, if i had the cash is pick those manifolds up for the hell of it
