Choke Heater Tube

The choke housing on the carburetor has a restricted journal to vacuum, which draws air in from the fiber-wrapped heat tube. The tube comes from a fitting on the exhaust manifold connected to a pass-through tube that collects heat from the exhaust. The pass-through is fed with fresh clean air by the tube coming from the top of the carb.
