Early 70’s Ford Truck, Motocraft 2150 Carb (with auto choke)
The auto-choke has a small tube going to it. It seems to originate in the exhaust manifold area.
Does this tube pipe hot exhaust gas to the choke? Or does it simply pipe hot air using convection?
The reason I’m asking is the tube has rusted off and become disconnected at the exhaust manifold, and I’m trying to decide what to do about it. Is it now leaking exhaust fumes?
