Automatic choke system

An automatic choke system for use in an internal combustion engine having a heat source and a choking mechanism including a choke plate, the choke system comprising:

• a first structure that is thermally responsive;
• a second structure connected at least indirectly at a first end to the first structure and at a second end to the choking mechanism;
• a heat transfer channel at least indirectly linking the heat source to the first structure, wherein the heat transfer channel enables fan-propelled heated air to proceed from the heat source to the first structure and thereby allows for convection of first heat to the first structure, and additionally allows for conduction of second heat from the heat source to the first structure,
• whereby the first and second heat received at the first structure causes a response at the first structure, which in turn causes the second structure to operate so as to effect a movement of the choking mechanism.

A heat activated choke system for use in an internal combustion engine having a heat source and a choking mechanism, the choke system comprising:

• a module including a thermally responsive first structure, the module being mounted directly upon the heat source such that heat from the heat source is conducted to the thermally responsive first structure, wherein the heat source is a muffler;
• at least one linking component coupled to the choking mechanism, wherein actuation of the at least one linking component cause actuation of the choking mechanism;
• and
• an additional component linking the first structure to the at least one linking component, the additional component spanning a majority of a distance separating the heat source and the choking mechanism,
• wherein the additional component experiences rotational motion upon actuation of the first structure.
