Yes. Ground the black wire with a yellow stripe at the carburetor connector to the device box. Do so by soldering an extra lead to the black/yellow wire that you can ground with a ring connector. Doing so essentially grounds the MCS, causing the carburetor to go full-lean. You will have to back the mixture screw out quite a ways to get your idle back but it will lean your mixture down enough to pass emissions. Don't ask me how I found out about this fix, err..hack. But suffice it to say, it will get you through the smog test unless there is a major mechanical problem with the carburetor such a a sunk float or a ruptured gasket. On my vehicle the extra wire can be attached to the device box under the hood come smog time, and then as soon as I pass smog I take the wire off and stuff it down in the vacuum hose bundle to keep it from contacting a ground and then I re-adjust the idle.

Your other option is to remove one of the wires to the MCS(yellow and red wires..the small ones) from the carburetor connector and tape it off or otherwise isolate it so it cannot complete the circuit. Without a dwell signal to the MCS you will run as lean as the carburetor will allow.

Good luck with it.
