Power off the Simplicity snow blower. Allow it time to cool down.
Locate the Simplicity snow blower's muffler. It will be found at the bottom left of the engine and has a number of bolts holding it in place. Remove these bolts with your socket wrench and slide off the muffler.
Take the dipstick out of the Simplicity snow blower's gas tank. Remove the bolts on the gas tank as you did with the muffler, then slide the gas tank off.
Begin operating on the now fully accessible carburetor. The bowl-shaped device will be found along the right side of the Simplicity snow blower's engine block. Position a pan or dish under the bottom of the carburetor bowl before proceeding.
Loosen the nut on the bottom of the Simplicity snow blower's carburetor bowl with your socket wrench. Fuel and liquid will leak out. Allow it to collect in your pan.
Remove the carburetor's nut. Twist off the loose carburetor bowl.
Drop the carburetor nut into a bowl of carburetor cleaning solution and allow it to soak, then scrub it with a wire brush.
Wipe the inside of the carburetor out with a cloth and the cleaning solution.
Reassemble the carburetor, gas tank and muffler by following the disassembly operations in reverse.
