Hello.
I tore all the accessories off my 318 (73 Dart) and while I was checking things out, I noticed that while my distributor's vacuum advance was hooked up (presumably to a properly sourced port on the carb), there was a plastic module marked "CARB" next to an two-vacuum port bit marked "Control Valve" on the far passenger side firewall. Pictures below.
What does this do, is it smog related? Can I safely leave it out of the circuit, or should I hook it all up again? What's the correct vacuum line configuration here?
