Having a clogged carburetor can cause all sorts of problems for your ride on mower, including a failure to start immediately, a loss of power while in use, engine flooding and a failure to start without a cooling-off period. This is because the carburetor is vital for ensuring airflow through the mower’s engine. If you believe that your carburetor is dirty, the good news is that you can clean it.
Step 1: Remove the bolt from the cover of the carburetor and the air filter; set them aside. Then, remove the bowl nut from underneath the carburetor. Pass a thin piece of wire through the hole to clean away any debris and use a small pick to scrape away dirt from the shaft.
Step 2: Spray the bowl nut with carburetor cleaner and use a brush to scour away any remaining debris. Wipe the nut dry on a paper towel. Spray the outside of the carburetor bowl with the cleaner and wipe dry with a paper towel to remove dirt. Remove the bowl entirely.
Step 3: Use the pick to scrape along the rim and in any indentations on the inside and the outside of the bowl; this will loosen any clinging debris. Spray the inside and the outside of the bowl with the cleaner. Use the brush to scrub the bowl and wipe clean with paper towel.
Once you are finished, you will be able to put the carburetor back together. If you notice that the air filter is overly dirty or damaged, you should replace it to ensure that your ride on mower runs as smooth as possible. If your mower still has issues starting, you will need to take it to a mechanic to diagnose an additional problem.
