When you begin to have lawnmower starting issues or you want to improve the mower's fuel efficiency, you may want to consider cleaning the carburetor. You will need to remove the carburetor from your Toro lawn mower to clean it properly. The carburetor on the Toro secures to the engine with a single bolt. To access the carburetor, you will need to remove the air cleaner housing and possibly empty the fuel tank.
Raise the air cleaner housing side of the mower and place wood blocks under the edge of the deck between the wheels. Gently lower the mower over the wood blocks. This will raise the side up just enough to give you a clearer view of the carburetor. Pull the spark plug wire end of the spark plug with your fingers.
Turn off the fuel cut-off valve under the fuel tank near the fuel line going to the carburetor. If your Toro model does not have a fuel cut-off valve, hand siphon the fuel from the tank into a gas can.
Remove the screw securing the air cleaner housing cover with a Phillips-head screwdriver. Pull the housing cover and the air cleaner filter away from the mower. Disconnect the screw securing the base of the air cleaner cover to the Toro carburetor with a socket wrench. Pull the base away from the carburetor.
Locate the two fuel line hoses going to the carburetor. One will be toward the back of the carburetor and one will be toward the front. The hoses slip over ribbed ports on the carburetor and do not use clamps. Pull the hoses away from the carburetor with a pair of pliers.
Find the single bolt that secures the carburetor to the engine housing. Turn the bolt counterclockwise with a socket wrench to remove the bolt. Twist the carburetor counterclockwise slightly to disengage the linkage and pull the carburetor away from the mower.
