An internal combustion engine includes a muffler configured to reduce exhaust gas noise. The muffler has a housing defining an interior and an exterior. A choke valve is configured to control a flow of air in a carburetor and a thermally responsive element is coupled with the choke valve and configured to move the choke valve in response to a temperature change in the thermally responsive element. A thermally conductive member has a first portion positioned in the interior of the muffler and extending through the muffler housing to the exterior of the muffler, and a second portion positioned exteriorly of the muffler and coupled to the thermally responsive element. The thermally conductive member is configured to conduct heat from exhaust gases within the muffler to the thermally responsive element.

An internal combustion engine includes a muffler configured to reduce exhaust gas noise, a choke valve configured to control a flow of air in a carburetor, a thermally responsive element coupled with the choke valve and configured to move the choke valve in response to a temperature change in the thermally responsive element, and a thermally conductive member. The muffler has a housing defining an interior and an exterior. The thermally conductive member has a first portion positioned in the interior of the muffler in direct contact with the exhaust gases and extends through the muffler housing to the exterior of the muffler. The thermally conductive member also has a second portion positioned exteriorly of the muffler and coupled to the thermally responsive element, the thermally conductive member configured to conduct heat from exhaust gases within the muffler to the thermally responsive element.
