Ross, the CIS is a black box to me, suitable only for magicians and those versed in the black (auto) arts. Jim D might be able to help. I know these systems are very pressure sensitive, and the internals really like to be clean - no sediment. Jim's website has some good k-jet technical info that might be helpful to you. Here are a few tech links if you want to sort through them:

Here is a CIS test rig that I find pretty useful:

It involves 8 mason jars (about $10) and 25 ft of 5/16 fuel line (about $30). You pull out the injectors and stuff them into the ends of the fuel lines. Run the fuel lines up the the mason jars sitting on the fenders. Key off, jumper the fuel pump on. Now you can play the the flappy valve and see how fuel delivered varies with air flow and vacuum, and from cylinder to cylinder. Its pretty redneck and qualitative, but if you want to go all science and quantitative you can add at $70 digital scale (e.g. Rubbermaid 1812588) and a stop watch and actually measure and chart the flow rate under different conditions.

At least in my use there are very little fuel vapors or smell.
