Still running rich

I am assuming you are talking about it being rich at idle because I doubt you would notice fuel smell in the exhaust at wide open throttle, I would go back to the jets that were in it so you don't lean out at wide open throttle, main jet's will have no affect on idle quality, check the power valve, float level a little under half way up the hole, then tune on your 4 corner idle screws, turn them all the way in one at a time, can you kill the car with the third one or can you turn them all in and the car still runs? do you have adjustable air bleeds on top of the carb, these would be the holes on the outside, the inside ones are high speed air bleeds
