passing gear on 350

[joebuick]

Hey Guys,,,,I scored a quadrajet in unmolested condition and went thru it just to look at the insides and looks like a new one. I installed this morning and the engine ran just great after the pump had give it some gas. I adjusted the air mixture screws with my new autozone carb adjuster screwdriver and man,,she just settled down and just patting its foot. I am real anxious to take a short trip and check the milage as the other carb was a guzzler as i never could get it to smooth out and would always run rich. Last time we went to the mountains I got 6-7 mpg,,!! whoa!!!! I'm betting 12-14 now, but will settle for 18-19.
The reason for this post is I need somebody to tell me how to adjust the cable coming from the tranny to carb. It was disconnected when we bought the truck and it must control the "passing gear" as it will not downshift no matter how hard you hit the go pedal. It is a turbo 350. thanks
