    I am not 100% sure but I believe that it is to help start the engine easier. I have seen a few guys in NASCAR doing that. If a car wont refire, a guy would spray something in the small air opening between the hood and windshield which is supposed to help the car restart easier.

    A few times if the mower won't start or having difficulity starting, I would usually take the air filter out, pour just a few drops of gas in the air filter unit, start the engine then reinstall the air filter. Be careful when doing that.

    If you are referring to the vapor canister under the hood of a street legal vehicle? it is an emissions control device to catch the fuel vapor from your fuel tank and prevent the vapor from escaping into the atmosphere. The captured vapor is pulled back out of the canister and burned when the engine is running via a vacuum line.
    If that is the fuel vapor canister you are talking about?
