I have a 1988 Seaswirl Sable with a brand new 5.7 litre engine, rebuilt Rochester 4 Barrel carb, and a new Carter fuel pump. I start the engine and black smoke comes out of the exhaust. Gas is all over the carburetor around the accelerator pump. I know the engine is flooded with gas. I have taken the carb off and the inside of the intake manifold has unburnt fuel in it. The engine, after about five minutes of running at 1000 to 1500 rpms will clean up and start running and idling fine. This only happens after it has been sitting over night. I have checked valves, timing, plugs etc. I have replaced the carb (again) and now I am in the process of putting the old fuel pump on on start the process of elimination. If you have some suggestions, bring them on.
