i have a 1982 mustang with a re manufactured motor craft carburetor. it is Single barrel, i am not sure but i think it is the 2700 v v but i don't have an id tag for it. i was wondering if anyone had a picture or diagram for the tuning screws. i know where the fast idle and slow idle screws are but i can't seem to find the air to fuel mixture screw to adjust it. i have had it adjusted before but now it is running rich again, last time i had it tuned the guy knew where the screw was but i cannot figure out where it is. i have searched the bottom of the carb and haven't found it. i also looked on the sides and top in case it may be placed differently. if anyone knows anything about these carbs please let me know i really need to adjust it.
