i need help on where to start! (carb setup)

i adjusted the timing and it helped a little. still wont idle and i couldnt find any vacuum leaks. vacuum pulses with engine between 5 and 10 at about 1500 rpm (lowest i could get it to run) and raises to 15 at 2000 rpm. throttle response is sluggish and the rpm lingers a while before dropping fast after i give it a little pump. i took apart the carb and this is what i found:

mains 73, secondaries 82, power valve stamped 45 im assuming this is 4.5 in/hg? all 4 air screws are 1.5 turns out. secondary jets are on standoffs, primary throttle plates are drilled either 1/8" or 3/32". primary bowl level is 2/3 up sight glass and secondary level is halfway.

to me it sounds like its rich so i dont know how its acting lean. i would upload pics but i dont know how to post them here. any ideas would be greatly appreciated, im frustrated and confused :banghead:
