Carb Help!!!

I thought the 800 CFM was to big as it ran so rich. It almost smelled like fuel coming out of the exhaust pipes. I did put new springs in it, played with the timing, adjusted the mixture screws but it just seemed to big. Maybe I am totally wrong and it needs to be tweaked, again no carb expert here by any means. I did rebuild using instructions and bought the edelbrock rebuild kit for the 600. The gasket matched the old one I took off.
