For those of you without broadband to download all the pictures, in a nutshell...The nozzles have a brass tube that the nitrous flows through that is sealed off at the very bottom to keep the nitrous from backing up into the fuel channel.
It seems many of these nozzles were made with tubes that were too short... so they don't seal. When the nitrous is engaged, the nitrous backs up into the fuel channel and keeps the enrichment fuel from flowing!
People were actually seeing an INCREASE in fuel pressure when the bottle was activated... as the nitrous would actually back up into the fuel side of the system and often peg the gauge! When you've got 1000psi of nitrous pressure and 6psi of fuel pressure... you better have a good seal, or a better design!
There are pictures at the above link that illustrate exactly what the problem is.
