Aviat Aircraft has redesigned the carburetor heat box for the Husky, attaching a more robust lever arm that hosts a new swivel pivot to which the actuator wire is attached. The dampener is now attached to the new box via bushings which reduce friction and enhance service life.

The bottom of the carb heat box is covered with a wire mesh screen which prevents debris from entering the induction system. All models of the Husky can be retrofitted with the new carburetor heat box which is now standard equipment on new copies of the popular Husky A-1C.
