How to Clean a Lawnmower Carburetor

Overview

During the life of your lawnmower, you will have to do lots of maintenance procedures, few being more stressful than cleaning out the inside of the carburetor. The carburetor is the component of your mower's engine that mixes air and fuel together so that your mower will start and run. When contamination such as dirt, fuel or oil from a tipped mower gets into the carburetor, it will need to be cleaned out before the mower will work properly.

Step 1

Put on your safety gloves and goggles before starting your work.

Step 2

Remove the spark plug from your lawn mower using a ratchet to prevent the machine from starting while you are working on it.

Step 3

Take the carburetor off of the engine by removing any nuts that hold it into place. Keep a plastic tray near the work area so that you can place the nuts in a safe place.

Step 4

Remove the top nut off the bowl at the top of the carburetor, and turn it upside down to allow any gas to drain onto the newspaper. Separate the two sides of the carburetor.

Step 5

Take off the plastic components of the carburetor, and spray the rest with the carburetor cleaner. Wipe off the excess spray with some old rags.

Step 6

Spray the plastic components and the rest of the carburetor with the compressed air to remove any dirt and dust from the components. Wipe out the inside of the carburetor bowl.

Step 7

Replace all the carburetor components in reverse order, and turn on the mower to test its functionality.

Tips and Warnings

  • Do not clean the carburetor near any open flames, and work in a well-ventilated area to protect you from the carburetor fumes.
