An autochoke controller which suppresses cost with the starting property upon a high-temperature reboot maintained favorably with a simple constitution without using an autochoke-only thermostat. An autochoke controller which has engine temperature sensing means (6, 61) connected to a control circuit (60) and the drive of which is controlled via the control circuit (60) according to an engine temperature comprises a self-holding circuit (64) which connect a switch sensing circuit (62) for sensing the on/off actions of a main switch (2) to the control circuit (60) and self-holds the power source of the control circuit (60) when the main switch (2) turns from on to off.
