The vertical cable is the throttle cable, the horizontal one is
the choke cable:

This is a 1950, 216 with a Carter W-1 but it's the same cable
setup as the Rochester B carb. The throttle wire is routed thru
the hole in the vertical throttle link and that is all that is
the only retainer for that link. It has a brass stop at the end
of the wire that is shown in the picture.
