Rochester Carb Adjusments on 1980

[sac001]

Does anyone know how to properly adjust the Rochester Carb on a 1980?

I can't see any adjustment screws other than the fast idle and choke.

Thanks,
Steve

they use a clutch head screw and you can buy a flex driver at any napa for about $7.00

No help for you here Steve, just wanted to welcome you back buddy. Haven't seen you here in a while.

The idle mixture screws (2) are at the front, in the baseplate, in line with the two primary venturis.

Eric, thanks for the welcome. I've been here, just not as much, and pretty much in stealth mode.

John, thanks for the tip, I'll check it out tonight.

The idle mixture screws MAY have plugs on the front. I believe that in order to be 50-state legal, Edelbrock presets the idle mixture and seals the adjustment holes -- just like what was originally done with the Rochester QJets.
