Nice job!!!
If you need to lean it out any more in the future, then just swap out the .072 IAB's for some .075/.078's or something in that area then reset your in D idle vacuum again and test again. Do what you can to keep the four metering screws between 1/2 - 1 turn out. These QF carbs don't like much more than 1 turn.

You now need to go out and drive it for a while to clean up those plugs. Have fun!
