What is this lever thing on a Carter BBD

On my carter BBD there is a metal piece the best I can describe as a lever, though it doesn't look like it connects to anything or actuates anything. If you manually raise up you can get it to move the Tb just a little, but I don't see how anything would do with w/o actually moving it with your fingers. It can be moved freely nearly 90 freely without moving anything else.. Does anyone know what this is??

The part I'm speaking of is this piece held on with the flat head:




It can be moved freely as I said, here are the two max positions in the free movement:
"resting" position

If you move it up with your finger:

Take another picture with something touching what your questioning.

Everything I see in the picture looks correct.

The black round thing is the electric choke. It pulls on the horn that is attached to the choke plate shaft with the flat head screw. The vacuum operated thing (some will call it a vacuum motor) with the linkage with all the bends is the choke pull back. It's job is to pull open the choke plate .095 inches as soon as the engine starts.

Below is a link on how it operates correctly.

It's this piece, in the other pics you can see that piece has moved a bit. Sorry meant to add the red circle. It really seems to have no effect and just loosely can be moved about.

Did that use to connect to the dash pot?

Your profile is not filled out and it is not clear how old your BBD actually is.

These carbs can be quite complex, the equipment bolted to them over the years has changed.

It's a 1976 cj5 with a 232, though i'm not sure its the original carb, looks like it was reman from 86 96 or 06 the sticker was really faded and torn. The part circled doesn't seem to be connected to anything except where it is mounted to the pivot point, nor does it look like it could connect to anything. Though, If you push it up with your finger all the way till it contacts where the electric choke connects to the carb it will hit a lever on the TB and open the TB a little, but it doesn't look like anything would ever make it do that other than your finger.

EDIT: in all the pics I've been finding the dashpot is on the throttle linkage side. I may be wrong though.

Here is a pic I found of another one that also looks like it is connected to nothing.

It certainly looks like the tang that the dash pot rested / pressed against. It was a little damper that slowed the closing of the throttle to fully closed when you took your foot off the gas. Not all BBDs were fitted with the dash pot and they were not in contact above about 2500 rpm at rest.

That does seem to be the most logical case, the only images i've found of a dashpot on a BBD are these, and its on the wrong side. But who knows with these old carbs. I'm going to go with this theory and not worry bout it. haha

Those are not dashpots, look like solenoids.

WOT (wide open throttle) switch tab. Yours has an outer tab I haven't seen, but the inner / shorter arm is for a switch that is on a bracket that is supposed to be between the choke housing and carb body.

I got a 232 two barrel at home with the same lever arm.

I know there was no WOT that year...
But there was no electric choke either...



I'm gonna have to look at my 84 though. I could swear there was a dashpot on there as well as a WOT switch.

Yeah, i'm not quite sure, I'm almost positive that this is an aftermarket reman carb. So with that being said, who knows. Maybe it is an older year core, that had an elec choke put on during reman. The way it operates really looks like it could actuate a dashpot, allowing the throttle to not be slammed shut when you get off the gas.

Did the mopar version have that? May be its a combination of what Holley or whoever had in their box of parts.
