Carburetor cleaning solution
The Toro snow blower can suffer from a a leaking carburetor nut, a build-up within the carburetor bowl or a general excess of oil within the snow blower's oil reservoir. You can fix all potential Briggs & Stratton engine flooding problems without the use of any special tools. Previous knowledge of operating on flooded engines and Toro snow blowers in general is not a requirement to fix your machine and can help you avoid costly manufacturer repairs.
Find the Toro snow blower's carburetor. The carburetor is located along the left side of the Toro's Briggs & Stratton engine assembly.
Locate the nut on the underside of the distinctive bowl of the carburetor. Place a pan or dish under the nut.
Loosen the Toro snow blower's carburetor bowl nut and wait as fuel and liquid finish leaking out into the pan.
Remove the visible bolts securing the carburetor bowl to the rest of the engine with your socket wrench, then twist off the bowl with your hands.
Clean out the liquid and build up within the snow blower's carburetor bowl using a cloth and some carburetor cleaning mixture.
Set and twist the carburetor bowl back into place and tighten the nut into its underside with your socket wrench.
Check the air filter on the end of the snow blower's carburetor. It may have become flooded with oil. Disconnect the air filter from the carburetor if this is the case by removing the bolts and screws that hold it to the engine using the wrench and a Phillips screwdriver, respectively.
Use a cloth to wipe off the end of the air filter after cleaning it with your solution and blasting it with warm water. Allow it to dry and then reattach it to the motor with the removed screws and bolts.
Survey the amount of oil in your oil reservoir by measuring with the dipstick on the middle rear of the machine. Excess oil in your Toro snow blower may have caused your flooding problems in relation to the air filter and carburetor. Ensure the oil line does not come up beyond the "high" hash mark on the dipstick.
Place a pan under the oil drain plug on the bottom of the rear of the Toro snowblower if the oil level was too high.
Unplug the oil drain plug to drain excess oil. Plug the drain back up when you are finished. Remeasure the oil level with the dipstick as required to check your progress. The oil level must be between the "low" and "high" marks.
