So was having power issues. Replaced battery, alternator, voltage regulator. Just did the full deal so I would cover the bases. The old alt had positive cable with a splice connected to one of the prongs, the ground wasnt even connected. The old voltage reg was removed and two of the wires were connected together. Seems like prev owner was trying to run it/wire it for internal regulated alternator. But the old alt was not internally regulated.
Anway, I got the wire diagram from Buick and got the correct alternator, correct voltage regulator, and wired up properly as far as those two go. It fired right up. Within 60 seconds started to stutter. Pressed more on gas and it stayed running but was starting to choke. Voltage stayed within 14ish. Let off gas and died. Black spray near exhaust and a pool of gas under carb. Help.

Well take the air cleaner off and see if hte choke plate is opening up just a hair after starting. Ther should be a choke pulloff pulling plate open and not letting it blow balck out theexaust. There is a little hose going to it and either the pulloff is bad or the hose has a hole or cracked. Also if it is putting gas in like to much the needle and seat are stuck probably. You can either rebuild the carb or beat it lightly with a small hammer to break it free. Then what i've always found to work is rev the engine up and close the choke plate by hand, then open it. Keep doing this for a little bit, ike a minute. That pulls fuel through the needle and seat and alot of times cleans it out. Then do all your adjustments to the carb.
