Carb is whistling at hot chicks...and dudes.

the carter bbd, is all of a sudden whistling after warming up. Only at idle. If i give it gas, stops.
Only thing I did was advance timing a bit.
Does that make any sense?

I removed the air cleaner, it is whistling directly down the throat of the carb. no change if i mess with mixture screws. help??
