What Are the Symptoms of a Bad Carburetor on a Push Lawn Mower?

Zero idling of the engine on a push lawn mower is a direct symptom of the carburetor being bad.
It is because due to the improper mixing of fuel and air, the carburetor delivers a wrong mixture to the engine. Consequently, the engine won’t idle with this fuel and may start stalling.
2. No Acceleration Detected
With the command for acceleration, the carburetor has a duty to deliver more fuel to the cylinders.
But, once it works with a faulty component, the flow to the cylinder may not increase or completely stop. As a result, the acceleration of a push lawn mower is not detected.
3. No starting of Engine
The engine on a push lawn mower facing toughness in starting means the carburetor has some issues.
The starting problem rises when the carburetor gets less air flow than the fixed ratio. And, that is caused by the carburetor’s damaged components.

As it doesn’t mix the fuel and air as per as required, the black smoke is encountered. And, it will continue to come out till the carburetor mixes the fuel and air correctly.
5. Imbalanced Running
Imbalanced running of your push lawn mower is mostly invited by a carburetor that is not delivering enough fuel.
The mower may start but the running performance deteriorates as the carburetor gets difficulties in flowing the mixture. Since the flow is not regular, the mower follows a rough running.
