INTAKE MANIFOLD
The intake manifold is cast aluminum and has a single
level design. A cast passage in the manifold allows en
gine coolant to pass through to utilize hot coolant heat to
warm the manifold and carburetor. This results in bet
ter fuel vaporization. An EGR port is also cast in the
manifold and receives exhaust gas from an internal ex
haust passage through the cylinder head.

WARNING: The battery negative cable must be re
moved to prevent a potential fire hazard when the fuel
pipe is disconnected.
