i bought the edelbrock 600cfm carb. (part # 1406) and i have know clue how to adjust it, so i just threw it on the car and it runs but really rich. how can i lean it out?

swap the primary jetting and secondary jetting.

this will be a step in the right direction.
By swaping the .098 primary jets for the .095" stock secondary jets you will lean down the low speed and cruise "jetting by 12% and lean down the primary full power jetting by 4%
Secondary jetting will be richened 4%
for more tuning you'll need to buy a tuning kit
consisting of jets, metering rods, power step springs etc.

you can read all about tuning edelbrock carbs here

read it, know it, there will be a test.
edelbrock carb do not like too much fuel pressure.
How much fuel pressure do you have at idle.
Should be 6 psi.
While you have the top off the carb swapping jets you can check the float height setting.
