Failed Emissions test with carb'd '85 - what to do?

[autoX]

The test was done with a 4-gas analyzer. The test I had to pass was the "enhanced test" where they run the car on a "dyno-type" of resistance drums and do about 6 traffic simulated accelerations from zero to about 30 mph. The two places I failed were:
THC - Standard Max = 2.00
- My car Max = 4.22
CO - Standard Max = 32.0
- My car Max = 55.5
FYI the other two results were:
NOx - Standard = 3.70
- My car max = 1.25
CO2 - Std. Max = N/A
- My car max = 731.8
Now for THC, the car spiked up right about the time the car hit 28-30 mph. Actually the same for CO. I don't know if it spiked up as soon as he let off the accelerator pedal or what. Man, I wish I had a scanner so I could send this to you! I do have a Fax machine!?

They did lift the hood on the car. I threw the stock (i.e. HUGE) dual-snorkel air cleaner assembly on the car, so if there is something that can be done underneath that, we are fine. They did NOT remove the aircleaner lid or anything...
Putting the stock carb on the car would take away all the fun. I want to make this thing pass with an "illegal" carb on it!?

BTW - it is only a 570cfm Holley Street Avenger carb. It has vacuum secondaries and an electric choke (which takes forever to turn off it seems! It idles high until the car is fully warmed up, even though the choke is turned down almost the whole way!)

Well, hopefully I have given you enough clues to be able to help me out. Let me know if you want me to fax my test results to you!

Thanks a ton,
