: Exhaust spitting black soot...?

I own an '87 Fleetwood Brougham "y" vin#; It so happens that when outside temperature goes anything below 60 degrees, the car will start only a cylinder at a time; starts firing one for 5 seconds and then the next one, for about 5 seconds too, then the third one and so on until all cylinders fire up, and in the process, there comes a cloud of black soot and smoke out of the exhaust pipe... I don't know what can be causing this... the carb has been just recently replaced with a rebuilt one of the same specs than the old one, wires and plugs replaced about a year ago... any ideas will be hugely appreciated!

check your cap and router button.

Have someone verify the choke system is adjusted to spec. Sounds like its adjusted too rich or the choke break is misadjusted. Black soot is normal on a cold morning mixed with water vapor, but if the soot is dry and black then the choke most likely needs a cold start adjustment.

Will do that... thanks for the suggestion!

I'll have that checked too... however; is it normal that the car starts one cylinder at a time when it's cold?
