If your idle speed is adjusted properly (not too high), yet you can visibly see fuel entering the venturi, it may be because of check balls sticking within the circuits that aren't supposed to be working at idle, or internal gaskets leaking, or more often, a problem with the float level, which causes fuel to "spill" over the top, in an uncontrolled fashion. This causes CO levels at idle to skyrocket, which in turn will tax the catalytic converter (if equipped). This spilling is usually accompanied by an erratic "spitting" sound, and may cause erratic idle speeds as well. The cure for such a condition is inevitably a carb overhaul for best results.
