Hi Everyone Out In Chrysler 300 Land! Slight problem or so I hope. When I pump the accelerator once to start the engine, it kicks over, starts, and runs rough for a couple of minutes! There is black soot exhaust on the floor of my garage. After a couple of minutes she just runs just fine. I live in Florida so it can't be due to "cold weather"! The carbs were rebuilt some few months back so I don't think or hope that it is not that. Any suggestions. Thanks and Happy Chryslering!
