Question 96 Prostar 350 TBI black smoke

Last two times out I have started to notice black smoke at idle. It seems to get worse as the engine warms up. In the past the engine has always had a little white smoke at startup, but nothing like this. Motor isn't using any oil. I have also noticed a significant amount of black soot build-up above the swim platform. Motor is the standard 350 TBI. I have always thought that it has ran a little rich since I have owned it just based on the smell of the exhaust? Any help would be appreciated.
