How To Clean Carburetor On Riding Lawn Mower
I’ll never forget my first ride on a riding lawn mower. I was eight years old, and it felt like the most powerful machine ever created by humankind. Of course, since then I’ve learned that even the mightiest machines need care and maintenance…like my current riding lawn mower, which has been giving me trouble with its carburetor lately. When your riding lawn mower starts sputtering and making strange noises, you may think it needs to be replaced or repaired right away. But before going through all of that hassle (and expense!), try cleaning the carburetor yourself! It’s easy if you follow these simple steps:
Step 1: Disable the spark plug
To begin, you will need to disconnect the spark plug from the spark plug wire. Using a socket wrench or ratchet, unscrew and remove the spark plug cap. Be sure not to damage your spark plug wire as you do this!
Once you have removed the old plug, insert your new one back into place.
Step 2: Disconnect throttle linkage
To disconnect the throttle linkage, you must first know where it is located. Increasingly, lawn mowers are coming with electronic throttles that do not require a linkage. If you have an older riding lawn mower, however, this step may involve removing some parts of your engine or air filter assembly to access it.
- Remove the air filter assembly if necessary in order to access the throttle linkage.
- Unscrew a screw from under your fuel tank and push on a spring loaded tab so that you can slide open the area that houses this part of your carburetor system: Your choke lever will be there as well (if your lawn mower has one).
Step 3: Drain carburetor float bowl
In this step, you should remove the float bowl and replace its gasket. You can find the float bowl on top of your carburetor. The best way to remove it is by using a screwdriver to pry it off. Be careful not to scratch or damage the carburetor during this step! Next, drain all of your fuel out of the carburetor by loosening screws and removing hoses connected to either side of where you removed your float bowl from. Now you can clean any debris left behind in your engine by spraying down it with an aerosol cleaner or by turning over several times with an old rag wrapped around something sturdy like a stick so that dirt falls out into another container below (if applicable). Once everything has been cleaned thoroughly, reattach both sides’ hoses and tighten them up before putting back together again with new gaskets where needed—don’t forget about those!

Step 4: Remove carburetor from the engine
- Remove the air filter.
- Remove the throttle linkage.
- Remove the carburetor.
- Disconnect the throttle cable from the carburetor and pull it out of its groove in your lawn mower’s engine block, or remove it completely if you have a hand-pull starter on your machine and don’t need to use a keyed starter cord to get it started.
- Unscrew and remove each fuel line clamp on either side of your engine’s fuel tank, laying them aside when finished with one side at a time so that they don’t get mixed up; then disconnect each corresponding fuel line from its respective hookup point on either side of your lawn mower’s engine block (or where ever else such connections are made), pulling any slack out as needed before removing any clamps, ties or other fasteners as well as any lines themselves from their connections points
Step 5: Inspect the carburetor for deposits and other debris
Inspect the carburetor for deposits and other debris. If you see any, take them off with a soft toothbrush or a piece of clean cloth.
Check to see if the carburetor is damaged or cracked in any way. Look at all of its parts, including throttle linkage (part of your riding lawn mower that connects engine throttle pedal to carburetor), throttle cable (the actual wire that connects from lever on handlebar) and choke linkage (the valve that controls how much air goes into engine).
Step 6: Clean and rebuild the carburetor (optional)
If you have the time and want to take your lawn mower to a whole new level of cleaning, you can clean and rebuild the carburetor.
This involves using carburetor cleaner to remove all of the dirt and debris from inside the carburetor. Then, use a carburetor rebuild kit to replace all seals, gaskets and diaphragms in order to ensure that it will work properly again.

Cleaning and even rebuilding a carburetor is an easy job, but it can be messy if you don’t take care to contain any spilled gasoline. Be sure to wear gloves, goggles and old clothes while working on this project.
