What are the common reasons why a lawn mower fails to start when cold?
When a lawn mower fails to start when cold, it can be due to several reasons. One of the most common causes is a faulty spark plug. A spark plug that is worn out or dirty may not be able to generate the necessary spark to ignite the fuel in the engine, making it difficult to start the mower. Another reason could be a clogged air filter or fuel filter. If the air filter is clogged with dirt and debris, it can restrict the flow of air to the engine, making it hard to start. Similarly, a clogged fuel filter can prevent the flow of fuel to the engine, resulting in starting issues.
In addition to these reasons, a lawn mower may also fail to start when cold due to a low battery or a faulty ignition coil. If the battery is not fully charged or is old, it may not have enough power to turn the engine over. A faulty ignition coil can also prevent the engine from starting by disrupting the spark that is needed to ignite the fuel. It is also possible that the fuel itself may be the culprit, especially if it is old or of poor quality. In this case, draining the old fuel and replacing it with fresh gasoline may resolve the issue. By identifying and addressing these common causes, you can increase the chances of successfully starting your lawn mower when it is cold.
