carb question
I have a 1974 Ford F100 4x4 automatic 360 engine. It has the 2bbl Motorcraft 2100 carb on it. I had to get a reman from Autozone. I think I have got my timing issues worked out, but the carb seems to be running real rich. Tail pipes are even wet. I know where the air fuel mixture scews are, but do not know for sure the direction to turn to lean the carb. If anyone has the answer to my question, or knows what I need to do to correct this problem, please help. Thanks in advance

with engine cold.. push accelerator to activate choke..
inspect choke plate for correct setting.
1/8" from completely closed
Now ,mictire screws:
They are only for idle mixture...... you know that right ?
Turn them into just about snug (be careful: turning them in too far will damage needle/seat area)
Now, back both of them out 1 1/2 turns
start engine and get engine to normal operating temp with choke fully off.
Set idle at 550 rpm
Turn ONE screw only in until engine starts to stumble
Now, while counting turns.. turn counter clockwise until engine starts to stumble.
Now divide the amounts of turns from stumble to stumble in HALF and turn the screw back in that amount.
Reset idle to 55 rpm and do the other idle mixture screw.
Next cold start up inspect choke plate again
