If you leave a manual choke on several minutes after starting the mower, the carburetor will likely flood up, leading to starting failures the next time you try to start up your lawn mower. While some chokes are automatic, some mower motors have manual chokes that the user has to turn on and off by themselves. Its function is to block the airflow for improved suction and consequently facilitate a more efficient engine start-up. The choke is a shaft-mounted valve within the air intake chamber of the carburetor. When the engine does not get enough oxygen that helps with fuel combustion when the spark plug ignites your lawn mower won’t start. Over time, the air filter could get clogged up, thus affecting the flow of oxygen to the engine. The air filter on a carburetor cleans the incoming air of dust and other debris that could cause damage to engine parts.
