Carburetor on a Toro Snowblower Leaks

Air Filter Cleaning

• Find the carburetor on the left side of the Toro snowblower's Briggs & Stratton engine. This carburetor is distinctive thanks to the bowl on its bottom. The square air filter is attached via bolts to the end of the carburetor, above the bowl. Loosen and remove these bolts with a socket wrench to disconnect the air filter for cleaning. Use a soapy warm water mixture and a cloth to clean the end of the air filter gently. If the Toro snowblower was tipped over and the oil reservoir on the machine was filled too high, excess oil may have reached the filter, requiring this cleaning.

Carburetor Bowl Draining

• Find the nut on the bottom of the Toro snowblower's carburetor bowl. This nut may have already have fluid leaking out from around it. Regardless, place a pan under this nut and loosen and remove the nut by twisting it counterclockwise using your socket wrench. Excess gas and fluid that can build up in your carburetor will flow out of the bottom of the bowl and into your pan. Wait for this process to finish.

Carburetor Bowl Cleaning

• Use your hands to unscrew the Toro's loose carburetor bowl now that the nut has been removed. Use carburetor cleaning solution and a damp cloth to wipe out and clean the inside of the carburetor thoroughly of any buildup and leftover fluid residue.

Reassembly

• Screw the carburetor bowl back onto the Toro snowblower's engine using your hands, and then secure it by reinserting the nut into the bowl's underside and tightening it with clockwise turns of your socket wrench.
