sounds like you have it to lean/rich. Follow this chart and it will point you in the right direction. First bring you needle settings out a bit (factory settings), if you don't know your factory settings start with you LSN flush with the carb body and your HSN 3 turns out. get you car to idle good (you might have to lean the lsn a bit to get a good idle.) once you get that right follow this chart.
If this doesn't help, you have a air leak.
