Thermostatic Air Cleaner: Description and Operation
Heated Air Inlet Dual Snorkel System
The dual snorkel air cleaner performs basically like a single snorkel air cleaner except that on deep throttle acceleration, both snorkels are open (when
manifold vacuum drops between 5 inch Hg).
The ``non-heat'' air snorkel is connected to manifold vacuum through a tee in the vacuum hose between the carburetor and the sensor.
Check the second snorkel vacuum diaphragm as one with the heat connector.
