Like all other household equipment, regular cleaning and maintenance is necessary to boost the efficiency of your lawn mower and extend its lifespan. The carburetor is a vital component of the mower and must be kept clean to encourage smooth operations. As you undertake your regular cleaning of the mower, be sure to pay close attention to the carburetor. Thorough cleaning assures you of enhancing the performance of the machine when in use. You can also avoid problems such as frequent stalling of the engine if you are careful to keep the carburetor clean. Following is a simple to-follow guide that will get your lawn mower carburetor clean.

Step 1 - Remove Deck

Push your mower onto a flat surface. Turn the fuel line to off position. Remove the mower deck and set it aside.

Step 2 - Remove Carburetor

Remove the nuts that hold the carburetor in place. Keep them away until later when you reassemble. Lay out some old newspapers or paper towels and pull apart the two sides of the carburetor. Any gas contained in the carburetor can fall onto the newspapers so that you avoid a mess.

Step 3 - Cleaning

Spray the carburetor cleaner all through the inside being careful to make sure you reach into all corners, small nooks and crevices. Grime and dirt tends to build up in the carburetor with continued use so be sure that you do a thorough job of cleaning out all the accumulated dirt and debris. Clean the two separate sides of the carburetor as well.

Step 4 - Compressed Air

Use compressed air to clean the plastic components of the carburetor. Do not use cleaner on these parts as the chemicals may corrode the plastic.

Step 5 - Wipe

Use a soft rag to wipe out the bowl inside the carburetor. The cup holds the gas that is fed into the mower. Wipe away all residual gas and dirt. Be careful not to use much pressure as you wipe. The carburetor is made of aluminum and too much pressure when wiping will distort its shape.

Step 6 - Reassemble

Fit back the two parts of the carburetor and replace all nuts and bolts. Place the deck back firmly in place.

Step 7 - Fire

Turn the fuel line on and tug at the starter. The mower ought to fire right away unless the fuel line is clogged or the air-gas mixture is improper.

Safety Tips

  • Avoid cleaning your lawn mower carburetor near any open flame. The cleaning agents are toxic and highly flammable.
  • Use safety goggles during the entire cleaning process. This will help protect your eyes from chemicals and blow-back that may cause you  injury.
  • It is best to do the cleaning out in the open where there is plenty of fresh air. This will help dissipate the emissions from the cleaning agents so that you are not subjected to stifling air.
