The 2 corner idle carbs also idle on the secondaries. its just not user adjustable.
Adjust the secondary opening as required from the baseline setting.
You do not want them completely closed. If the motor wants more base initial timing at idle give it what it wants.
try 24deg at idle.

If you want to play with the idle circuit get a AFR meter/gauge.
