That's good news - if you've freed up the rack you will no doubt find out more about how it is, or isn't, working, as you play around. A great first step. Get that #2 un-gummed (which should be easy now that it's also rotating) and make sure everything is working freely. I'm sure it will start to make sense.

The meaty portion of the space cam is really just the transition from one diameter to another - the fuel delivery map ends just at the part that starts to ramp up. No reason to think anything is wrong there the stylus looks to be hitting the right spot for 0% throttle. Be aware too that the fuel delivery for a given RPM actually goes DOWN as RPM increases, especially on something like a torquey sedan. The map shape is a bit more complicated than that but it would be easy to assume the opposite and think something was wrong internally because the rack moves towards lean at some point in the RPM range. You will not likely move the flyweights by hand out past a position equivalent to a few thousand RPM.

Any adjustment of any internal portions of the pump beyond what's necessary to get things cleaned up should not be necessary - if the car isn't running right, and the pump is un-gummed and working correctly, the poor running is most likely because of some other external system (like that whacky warm up system!!! I'm assuming the air valve provides some sort of automatic fast idle which is neat.

Hope my hasty answers are making sense!!!
