'87 RC--318 2B--High Carbon Monoxide

Hi Everyone...

Emissions Test here in Texas failed my baby today :-[

Everything is good except carbon monoxide at low idle (706) reading was 1.97 and it needs to be 1.20

Any suggestions?

Prior to last year's test (my first with my RC) I did the plugs, wires, cap, rotor and it passed...only put on 8k during the year. Is another tune up in order? I will pull a plug when engine cools...just got back...

Thanks All!

The mixture srews are sealed at the factory, take the carb off you should be able to see two metal caps covering the mixture screws. These need to be removed.
