Qjet ??, electric choke a must have?

[gjk5]

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

Just searched that site, they have a pictures page of chokes but no results returned for 4mv choke.

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.

You can get the divorced choke kit from Summit Racing.

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.
