You didn't state what year the car is (or which state's standards you are
trying to meet). When the car passed previously, was that after you
bought it or was the test run by the previous owner? If by the PO, that
leads one to suspect hanky-panky. In California, you can't sell a car
(that is eligible for testing) without it passing a smog check, which
puts a lot of pressure on the seller to make it pass "by hook or by
crook" (or by greasing a palm).
Or, more generously, the car was de-tuned just to pass the test and then
re-tuned for performance and drivability afterward. This frequently
requires little more than leaning out the mixture and setting the idle
faster for the test. But I really don't know anything about Webers, so I
can't say how one would adjust the HC downwards. But possibly someone
does...

Runs great,
looks particularly bad since some SUV clown backed into it.
If you're near Mountain View, CA,
it's the red one with the silver bootlid.
