tuning edelbrock carb for emissions?HELP!!??

[moturbopar]

hi all I took my 79 blazer through emissons today, it did well except on HCs on the loaded reading. Here is how it did.
idle HCs 110 max of 220
, COs 1.55 max of 2.00
loaded reading
was 281 max of 220
COs 1.35 max of 1.50

I tried retarding the timing a little but it really messed with the idle readings.
Anyways I was wondering if I should step down 2 jet sizes to reduce the HCs on loaded? The carb is a 1406 edelbrock performer. The jets sizes and needles are .97 jet with the .75x.47 rods.
I was going to change rods but they dont make any that are leaner. I have a set of .92 or .95 jets. Which should I try? I only have one retest and dont want to spend another $19 on another test. do you guys hink jets will help the HCs ?
Thanks
Shawn

which powervalve spring are you running. i think a 1406 comes with the yellow one about 4" hg you might try a couple of jet sizes down and a stiffer spring to try to keep more fuel out of the primary circuit until you need it
