Carburetor linkage Questions for 67 Dart

Have never installed a throttle cable so I have no experience with it.

How do you do a fine adjustment on the throttle cable using the metal sleeve that connects to the carb? Can you twist it right or left? Does it have to be disconnected first?

It looks like I have about 2" of cable showing and I assume that's the max amount it c/b adjusted?

From the picture you sent, the metal sleeve is held in the bracket by the pinch bolt. To lengthen the cable you loosen the bolt and slide the metal sleeve toward the carb. Reverse to shorten it. When the choke is off, you want the slack taken out of the cable. Have a helper put the pedal all the way down and look to see if the carb is fully open. That will be the best you can do.
And when you get the throttle cable adjusted, make sure you reattach the transmission linkage spring and adjust the linkage properly. Yours may be different than this one.
