Hi, I am potentionally going to trade my 1975 cutlass for a 1955 ford fairlane town sedan all original with a 272 and the 4bbl power pack option. The problem is that I'm pretty sure the carb isn't original, the choke is not hooked up to the carb. It doesn't idle without help from the accelerator pedal, and smoke comes out of the passenger side exhaust. It's a whitish color, maybe slightly blue. It sometimes is there, other times the smoke barley comes out. The points, cap, rotor,, wand wires haven't been replaced in a LONG time. Any suggestions? Thanks!
