I have a modified B20 that does not like a lot of advance below 3000rpm. I have the 123Ign set on 5 with max advance adjusted to ~31(no vac hooked up) at 4000rpm. John Parker says this setting for the B20A does not make full advance until ~4000rpm. I have the vac advance hooked up. It still runs a little lean (I have a AFR gauge installed) when under 1/2 - 3/4 acceleration below 3000rpm. I need to raise the needle clip in the Mikunis a knotch.
