Here's where you can find diagrams of the various Webers that fit:

For the DGEV/DGAV the accelerator pump jet/nozzle is #96. It looks the same although numbered differently for the other models. It's on the primary barrel and appears to have two nozzles. (I don't have a Weber so I have to rely on the diagram.) If one side is plugged, you may be able to clear it with compressed air, but you might have to remove the top of the carb to get to it the screw that holds the jet/nozzles.
