Now let's move on to the actual cleaning process of the lawn mowers carburetor. (Step by Step Process.)

Step 1- Ensure Safety First

Before cleaning anything of any kind, be sure to be in a well-aired space. Carburetors may have old fuels that can harm you, so you should work in an airy space. Open the door of your garage or turn on the ventilation fan.

Avoid cleaning your lawn mower carburetor nearby open flames as the cleaning agents are not only toxic but also highly inflammable.

Step 2- Assess the Problems

Your lawn mower may have problems besides the carburetor, so check to see if there is sufficient fuel, spark plugs, and ignition switches are in the right place and position. Also, check to see whether the air filter is clean and debris free.

However, if it appears that all of these are alright, then pour some carburetor cleaner in the carburetor and start your lawn mower, if it splutters, then it means your lawn mower has carburetor problems.

Step 3-Take Pictures of the Carburetor (Smart Thought)

In order to make sure you can piece it back together exactly as it was, take plenty of pictures so that it can guide you to put back everything together properly.

Step 4- Remove the Outer Casing

Use a screwdriver or a wrench to remove the outer casing to reveal the internal mechanics of the lawnmower. Also, remove the air filter and place the bolts and place them in a plastic bag to keep them safe as well as capture any fuel leakage.

Step 5- Unscrew the Carburetor

Use a screwdriver to unbolt the carburetor from its hold and also separate it from the fuel line. Use a rag to clean any oil spillage from both the carburetor and the fuel line. If, however, no oil fuel spills from the fuel line, then you need to clean the fuel line properly to free it from blockage.

Step 6- Inspect the Air Filter

Make sure that the air filter has nothing that blocks air from flowing to the carburetor. The main reason behind black smoke emission from exhaust pipes is an air filter filled with dirt or debris.

Step 7- Spray Carburetor Cleaner

Thoroughly spray carburetor cleaner in all the nooks and crannies of the carburetor. Clean both sides of the carburetor as well.

Step 8- Use the Air-Compressor Gun

To clean the plastic pieces inside the carburetor, use an air-compressor gun instead of any cleaner as they might corrode the pieces rather than clean them. Also for places that you cannot reach, use the air-compressor gun to clean it.

Step 9- Inspect the Wires

It is very important that you check the wires thoroughly because they can make your lawn mower useless. Check to see whether they are worn out or displaced somehow.

Step 10- Clean the Bowl

Clean the carburetor bowl first with a carburetor cleaner and then wipe it with a soft rag. As carburetor bowls are usually made with aluminum and wiping it with force may distort the shape.

You will see that the bowl is held in place with a nut which is really a spout (it has a hole), be mindful of cleaning it as well by scraping and cleaning it with carburetor cleaner.

Step 11- Don't Be Afraid to Replace Parts

If the carburetor bowl or the needle that is attached to the carburetor with a pin is too dirty, then instead of cleaning it, simply replace them. The same goes for that gasket in which the needle is placed.

Step 12: Reassemble the Parts

Now that you are done with all the dirty work (literally), it's time for you to reassemble all the parts. Remember the picture that you took; use them as a guide to reattach the parts piece by piece.

Step 13- Start and Go

Finally, cleaning is done. Why not fire it up? Even if you don't immediately start mowing your lawn, you should still fire it up to see whether it is running smoothly.
