A fuel evaporation gas treating device arranged such that when a vehicle engine is operated a heat-sensitive means detects the temperature around the engine and the fuel system and the like, and if the temperature is within a proper temperature range, a changeover valve allows a carburetor bore and a canister to communicate with each other so that a fuel evaporation gas in the canister is introduced into the carburetor bore and burned through reduction, and on the other hand, when the detected temperature is higher or lower than the optimum value, the changeover valve causes the canister and the carburetor bore to be shut off from each other as well as allows the canister and the atmospheric air vent to communicate with each other so that the secondary air is introduced into the carburetor bore, thereby to make it possible to automatically control the introduction of the evaporation gas and the secondary air into the carburetor bore.
