Induction air is taken from the right rear engine baffle, routed through a short duct into the filter housing,
and down to the carburetor through another duct and the carburetor air box. The filter housing, mounted to the
firewall, is supported by connections to the two ducts and by a bracket to the engine mount structure. The
c a rburetor air box is connected to the carburetor heat duct, which is additionally utilized as an alternate air
source should the main inlet become blocked.
