Hello-
My friend just bought a '76 cherokee chief. After starting it up, we noticed it was running VERY rich. It is blowing a little black smoke and once in awhile, it will puke out a a big black cloud. It is leaving black residue where the exhaust is blowing onto the ground (not oil). I live at 10,000 feet so carbs have to be adjusted for altitude. I think that the jets are already smaller than stock so I think there is another problem. The choke is opening like it should, the main jets are 46's, and the timing is where it should be (around 8 bdc). I think the needle and float are working ok. Anyone have any thoughts or does anyone know what the factory jet size for this carb is? By the way, the carb is a 2 bbl motorcraft.
