Robbie, the way I understand the operation of the accelerator pump on Delloto's is that the size of the jet varies the "time" the fuel is delivered and adjusting the rod changes the "amount" of fuel delivered.
I also believe adjusting the nut further down the rod increases the amount of fuel and lessens with the nut screwed off although I am prepared to be wrong here but before you start adjusting take out the pump jets and make sure they are not blocked, I usually take a strand of wire from a wire brush (brass if possible) and poke it in the jet hole then blow through it.....a word of warning DONT snap off the strand of wire in the jet hole
Here is an Alfa forum with a discussion that you may find relevant.
