OK, I started up one of the trucks the other day, and even after it was warmed up, with the choke wide open it was running very rich, to the point that I had clouds of black smoke coming out of the muffler and would flood out at low idle. Last time I ran it, it ran well.
Mixture screws were the same as before, and nothing else was changed.
Anything obvious to look for before I start disassembling the carburetor to look for somthing amiss?
Truck is 1960 F600, 292 V8, stock Holley 2 barrel carburetor with manual choke.
