How to Rebuild a Simplicity 3314H Carburetor

Locate the Simplicity's muffler on the lower left of the engine block. It is held in place by two bolts. Remove each bolt with a socket wrench.

Remove the dipstick from the mower's gas tank. Take the three bolts out of the gas tank with the socket wrench and remove the gas tank.

Locate the carburetor about midway down along the right side of the mower's Briggs & Stratton engine.

Take out the two screws on the rear of the carburetor inside the carburetor intake with a Phillips head screwdriver.

Twist the air filter on the back of the carburetor and remove it. No screws or bolts hold the air filter in place.

Remove the two remaining bolts on the carburetor intake with the socket wrench. This will free the intake from the rest of the carburetor.

Place a pan under the bottom of the carburetor bowl. The bowl is distinctly shaped with a rounded bottom.

Loosen the nut on the underside of the carburetor bowl with the socket wrench and drain any fuel and fluid into the pan.

Remove the nut in the carburetor bowl with the wrench. Set the carburetor pieces to the side now once they have been removed from the engine block.

Soak the nut in a bowl of carburetor cleaning solution. Clean out the inside of the carburetor bowl with the solution applied with a cloth.

Refasten the carburetor bowl in place by reinserting the nut into the bowl's underside with the wrench.

Reconnect the Simplicity carburetor intake to the rear of the carburetor with the two bolts you removed previously.

Twist the air filter back onto the back of the carburetor.

Replace the two screws you removed from the carburetor intake with the Phillips head screwdriver.

Slide the gas tank back into place on the mower and reinsert its three bolts with the wrench.

Set the dipstick back into place and reconnect the muffler to the lower left of the engine with the socket wrench.
