Rochester Choke Install

Purchased a new automatic choke assembly from Rick's for my 396/325 automatic with a Rochester four barrel. The unit went on fine and so did the connecting rod. The problem is the clip will not install properly not matter how I turn it. What am I doing wrong? Can someone email me or post a picture of this assembly?

Re: Rochester Choke Install

It has an odd shaped clip with two holes that stradle the little lever on the carb, the rod is enserted through, then the clip clips to the rod.

Let me if you follow this,..if not I'll shoot some photos.

Re: Rochester Choke Install

The choke kit came with a clip but I can't seem to make it work. A picture might help me. They may have sent me the wrong clip for my application. Thanks!

I've been hot-rodding and street-racing with Q-jets for 30+ years. These are great carbs when set up and tweaked properly. Post a pic of your problem showing the part you are talking about. I'm sure I (or someone else here) has an answer, but I'm not sure exactly which rod end you are referring to. Some of them use no clips.

In the pic below the choke linkage rod (part #1) uses no clips at all. This is a later model Qjet. Of course, there are many varieties of the Qjet, and your Qjet is most likely different from the pic, but you get the idea. The end of the rod goes into part #30 (lever), which is held captively in place in a small cavity on the side of the carb. The end of the choke assembly shaft (part #49) goes into the other end of the lever. The lever (#30) falls out of position once you remove the shaft (#49).

Re: Rochester Choke Install

Chevy SS,..good photo but it's the wrong one,..do you have another that shows a q-jet with the divorced choke,..the spring on the stove design? He needs see how the rod from the spring/housing stays attached to the little lever on the carb.

Ahhhh, ok, when he said "choke assembly" I just thought of the later-model setup above.

For the original factory style, with bi-metallic spring mounted on intake manifold, there's no clip at the bottom of the rod, it just goes into a loop on the spring and a slot in the cover holds in in place. The factory-style rod typically has a "U" shape in it, which allows for bending to adjust rich/lean choke conditions.

There is a crazy-shaped clip that holds the top of the rod in place. I rooted around in my toolbox and found one. Pic below shows it. I think this is what he is referring to. He may be missing this clip.

Re: Rochester Choke Install

Thats it Chevy-SS! The way the clip is made it will only fit one way to be able to snap on the choke shaft. On mine the lever holding the choke rod hits the top of the clip and it unsnaps. Have a pic showing how it is installed?

Re: Rochester Choke Install

Here's a pic of the clip holding the the rod in place. You'll notice, the clip I'm using for the demo is too big, but it's the only one I had laying around. It should snap snugly onto the rod.

Also, they made these clips in reverse style, to fit rods that would connect to the opposite side of the lever. It sounds like you are installing yours backwards, perhaps you got the wrong clip or you have the rod in backwards.

Yeah, I figured I could never explain that crazy clip without a pic. Glad you got it connected.
