Re: car's not running right
Why is it only running on three cylinders? Dry and wet compression test performed? If one of the cylinders is low on compression and is still being inected with fuel it's not combusting the fuel in that cylinder is probably causing a rich fuel condition. A rich running condition can cause black exhaust fumes and other symptoms:

Pull spark plugs and check for fouling? Do a power balance (drop) test. COmpression test if not performed already.

Dual Carbs, removed and what?
You have to balance dual carb motors and it's a process to do that. I'm assuming the carbs were rebuilt which definitely means they need tuning.
And since it wasn't tuned, I wouldn't be surprised if you ended up cylinder washing a cylinder by waaay too much fuel and burnt a set of rings.
