    Installed the new Carter YFA. My car had all the emissions removed prior to me owning it.

    I believe that I only need PCV , vac advance and trans modulator hooked up (non A/C).
    Is this correct?

    Also, there are (3) vac ports on the passenger side of carb, one on driver's side, and I have (5) coming out of the intake.

    I know where the pcv goes, but which ports are for trans and distributor?

    Also, the original carb had a manual choke cable rigged to it. I am missing a part for the choke, where it screws into the carb. Not sure what it is called or where to find it.

    Can this be converted to electric choke?

    Any help is greatly appreciated!

    Thank you very much!
    Jim P.

    All same manifold use any that fit, unused ports simply capped off

    great timely post. I was looking for the exact information.

    So If I am reading this right, I can hook up PVC to bottom of carb plate, then put the Vac advance and trans into the vac tree and cap all the other carb ports?

    Should work fine as described, anyone else see any problem?...
