Thermostatic Air Cleaner Vacuum Switch: Description and Operation

    When TAC inlet air temperature is below the switching point, vacuum from the carburetor port is directed to the distributor vacuum advance and the
TAC sensor. Above the switching point, vacuum is directed to the TAC sensor but not to the distributor vacuum advance.
