Paul,
On the DGV the accelerator pump jet is NOT calibrateable.

This 'richening' function is the equivalent of the heavier spring
of the SU carb.
On initial accel. you need a bit of extra gas getting in to compensate
for the sudden pressure drop opening the buterfly
the stiff spring of the dashpot piston, fighting the vacuum, causes
vacuum to suck gas rather than air until the piston could move up
to allow air in, thus temporarily enriching the mixture.
On a DCOE, this is the same as the pump/accel and backbleed jets.
