My buddy just bought a Buick 225 odd-fire for his CJ that has a 4 barrel manifold and Holley Carb. Havin alittle trouble findin some info on the carb. It's a Holley, vacumn secondares, mechanical choke. The only numbers on it are "list-1850-2" and "2802" Can anyone here find any info on this? Dorian?
