HELP! 88 Suzuki Samurai Won't pass emissions test BIG TIME!

I just failed my emissions test (Big Time)
CO2 levels at .99 except during decelerations.
I have seen info suggesting that I am running too Rich on fuel mixture, but
after a day online searching Google, Yahoo and everywhere else, another day
rereading the Haynes Suzuki manual (Which tells me it is too rich but not
how to correct it), and the last Hour at the library, I am still at a
complete loss.

I have posted photos at a website if you would take the time to look and
comment
www.castlerockinfo.com/zuki/index.htm

Please note the following from the photos,
Butterfly (Choke) is not open all the way as the Haynes manual suggests.
A part in the front left of the carb, ( A plunger with a rubber boot)
The boot is in bad shape and there appeared to be leakage around it
New muffler/exhaust shows Black Sooty deposits (haynes again says too Rich)
Where are the adjustments for Idle speed and Air/Fuel Mix??
The books often refer to test equipment that would be more expensive to buy
or rent, than replacing parts. So if you suggest replacing a few $5 - $10
parts to narrow this down that is much prefered to buying equipment or
paying the local "Import" guy.
Particularly since the local Import guy usually tries things that don't
workanyway.
(2 years ago emmisions test he spent 3 days and almost $200 then told me to
run it fast on the freeway and add 2 bottles of HEET before the test, I
passed barely.
You get the picture
Zuki is an 88 with 93000 miles only 4000 per year for the last 5 years
New Muffler (1 year)
O2 sensor (2years)

Please check out the photos and let me know
BTW Thanks for the links you gave the other guy I needed them too.
