In order to provide heat to the carburetor (to prevent carburetor icing) and to provide heat to me (to prevent Larry icing), you need to install a heat exchange muff around an exhaust pipe. It needs to be made of either stainless steel or galvanized metal. Because of price, I chose the latter and today I formed the outside of the muff. Tomorrow I hope to make the two ends and complete the installation.
