My snowblower leaks afetr the motor is turned off, don't know where to start looking

Does it do it if you loosen the gas cap?

Does your snowblower have a fuel shut off?

My snowblower does have a shutoff valve, but it still was dripping gas when I shut it off, my gas cap is tight

Take off the gas cap. Does it leak?

Is this a blower or a thrower? Throwers are the small guys with one fast moving auger, remove the plastic panel that hides the engine from view and you will quickly see your leak. It may be a bad carb bowl gasket or just a fuel line needs a tighter clamp.
