    I am getting rid of the Edelbrock Performer on my '72 this week, Auto Zone says they only have a 4MV manual choke and cannot get an electric for it (??). Is this a big deal? I have the manual choke dash in my truck so it will be factory, has anyone else living at a decent altitude (4,700) had any problems or am I better off looking for an electric choke model (so far only one I could find was at Napa and was double the $$)

    Should this carb be good to go out of the box (other than idle mix screw adjustments), or will it need to be rejetted or anything?

    Also, it is a Champion rebuilt Rochester, anyone ever use one of these?



    Anything else I should be prepared for going back to the Qjet?

    sells divorced electric choke modules

    I got a Holley rebuilt Qjet thru Autozone and didnt touch a thing other than idle speed, because you are at altitute you probably will have to tune for that, but should be ok otherwise

    4MV is the "divorced choke" you should have a flat spot on the manifold on the pass side of the carb, with a hole for a small bolt. that is where that module mounts

    I'll have to check around, I just checked pain old chokes on their site and no products came up as available, maybe I'm missing something.

    I had a manual choke on my '64 pickup, and I never used it.

    About the best operating choke setup I've had is the divorsed choke.

    I recently rebuilt one of my many qjets, decided to completely delete the chock stuff (it was a manual choke model). I even got rid of the linkages that keep the secondaries from opening.. only takes 3 minutes of idling for it to run fine here (but its never below 65)

    I checked. Summit only has them for the edelbrock performer qjets and the site says it's designed to fit a performer intake manifold.

    Dave I'm going to the salvage yard tomorrow, I'll see if I can find the stock divorced choke, the only difference will be the rod length. The housing and bi-metal coil are the same.
