Those are huge idles. Drop down the orifice size and to a smaller air bleed hole (not sure what F-number that would be). That should lean out your cruise mixture.
I recommend Keith Franck's hypojets. They are way better at fuel metering than the Weber ones, plus they're tunable - it's like having 4 jets in one. Going through the process, are now learning the differences between a "running" setup, an OK setup, a good one, and a great one.
