How to Remove a Lawn Mower Carburetor

Sometimes, removing a lawn mower carburetor is the only way you can clean and maintain it. If the carburetor gets water in it or becomes clogged with dirt, you'll want to take it off the mower to either clean it or replace it. This is a simple job that takes about 5 minutes to perform.

Tools and Materials

  • Hex wrenches (various sizes)
  • Pair of pliers
  • Disposable rags
  • Drain pan for used gas

Step 1: Drain Fuel

Drain as much gas from the mower into a pan. Some mowers will actually have a fuel shutoff switch on the line that leads to the carburetor, in which case you can simply flip this switch.

Step 2: Remove Air Filter

To access the lawn mower carburetor, you'll sometimes have to take off the air filter. This is attached with a hex nut and comes off easily. You should now be able to see the carburetor.

Step 3: Remove Fuel Hose

Place disposable rags under the carburetor to catch any fuel that drips. Using the pliers, gently pull the fuel hose out of the lawn mower carburetor. Take care not to pinch the hose.

Step 4: Remove Lawn Mower Carburetor

The carburetor should be attached with a single hex nut. Remove the nut with a hex wrench. Twist the carburetor to the side so it detaches from the linkage, and remove it from the lawn mower.
