What's wrong with this linkage

The linkage rod is wrong. Check out some of the AVS carbs on this site or on eBay and you will see what I mean.

If only it was that simple. This linkage rod is not removeable on the bottom.

Don't know if this helps. One that's been laying around for a while..........

HA 4611S

Top picture, choke wide open, all barrels open.
Bottom picture, choke closed, rear barrels restricted.

I have another carb, 4615SA, that I can use that looks like that and does work right. I'd like to keep the original carb on the car if possible.
