Gavin,

As Tippy said, you will want to be richer than 14.7 at idle. Something like 13.5 - 13.8. The engine will run cooler at idle with a richer AFR. What is your timing at idle with the distributor. You need to be 10 to 12*. Too much advance at idle can cause to the idle to hunt. Does your MSD retard the spark with increasing boost?
