As a homeowner, there’s nothing more frustrating than a lawn mower that refuses to start, especially when you’re ready to tackle that overgrown lawn. If you’re struggling with a Craftsman lawn mower that won’t start, you’re not alone. In this comprehensive guide, we’ll delve into the possible reasons behind this issue and provide you with a step-by-step troubleshooting process to get your mower up and running in no time.
Understanding the Basics of Lawn Mower Starting Issues
Before we dive into the nitty-gritty of troubleshooting, it’s essential to understand the basic components involved in starting a lawn mower. A typical gas-powered lawn mower consists of an engine, fuel system, ignition system, and electrical system. When you turn the key or pull the starter cord, a series of events unfolds, which ultimately leads to the engine firing up. However, if any of these components fail or are compromised, your lawn mower may not start.
Common Causes of Starting Issues
There are several reasons why your Craftsman lawn mower may not be starting. Some of the most common causes include:
A faulty ignition system, which prevents the spark plug from igniting the fuel mixture.
A clogged fuel system, which restricts the flow of fuel to the engine.
A dead battery or faulty electrical system, which prevents the starter motor from turning the engine over.
Poor maintenance, such as old or dirty oil, a dirty air filter, or a faulty spark plug.
Ignition System Issues
The ignition system is responsible for generating the high voltage needed to create a spark in the engine’s cylinders. If the ignition system is faulty, the spark plug may not fire, and the engine won’t start. Common ignition system issues include a faulty spark plug, a faulty ignition coil, or a faulty ignition module.
Fuel System Issues
The fuel system is responsible for delivering fuel to the engine. If the fuel system is clogged or faulty, the engine may not receive the fuel it needs to start. Common fuel system issues include a clogged fuel filter, a clogged fuel line, or a faulty fuel pump.

What are the common reasons why my Craftsman lawn mower won’t start?
The most common reasons why a Craftsman lawn mower won’t start are related to the fuel system, ignition system, or maintenance issues. Problems with the fuel system, such as an empty tank, stale fuel, or a clogged fuel filter, can prevent the mower from starting. Similarly, issues with the ignition system, including a faulty spark plug or ignition coil, can also cause startup problems. Additionally, maintenance-related issues, such as a dirty air filter or a loose connection, can also contribute to the problem.
To troubleshoot the issue, start by checking the basics, such as ensuring the tank is full of fresh fuel, the air filter is clean, and the spark plug is in good condition. If these checks don’t resolve the issue, it’s likely that there’s a more complex problem that requires further investigation. In this case, it’s a good idea to consult the owner’s manual or contact a professional mechanic for assistance. By methodically checking each potential cause, you should be able to identify and address the underlying issue preventing your Craftsman lawn mower from starting.
How do I check and maintain the air filter on my Craftsman lawn mower?
The air filter on your Craftsman lawn mower plays a crucial role in ensuring the engine runs smoothly and efficiently. To check the air filter, start by locating it, usually found in the engine compartment or attached to the carburetor. Remove the filter and inspect it for any signs of dirt, dust, or debris. If the filter is dirty or clogged, it’s likely that it’s restricting airflow to the engine, which can cause startup problems. To clean the filter, gently tap it against a hard surface to remove any loose debris, then wash it with mild soap and water.
Once the filter is clean, allow it to dry completely before reinstalling it. It’s also a good idea to replace the air filter at the start of each mowing season or every 100 hours of use, whichever comes first. A clean air filter will help ensure your Craftsman lawn mower runs smoothly, starts easily, and maintains its performance over time. Additionally, a well-maintained air filter can also help improve fuel efficiency, reduce emissions, and prolong the lifespan of the engine. By regularly checking and maintaining the air filter, you can help prevent startup problems and keep your lawn mower running at its best.
What should I do if my Craftsman lawn mower has a faulty spark plug?
If your Craftsman lawn mower has a faulty spark plug, it can cause a range of problems, including difficulty starting, poor performance, and reduced power. To diagnose a faulty spark plug, start by removing it and inspecting it for any signs of wear or damage. Look for cracks, corrosion, or excessive wear on the electrodes, which can indicate a faulty plug. If you suspect the spark plug is the culprit, try replacing it with a new one, making sure to use the correct type and gap setting for your mower.
When installing a new spark plug, be sure to follow the manufacturer’s instructions and take necessary safety precautions. Start by disconnecting the spark plug wire, then remove the old plug using a spark plug socket. Install the new plug, making sure it’s properly seated and gapped, then reconnect the spark plug wire. If you’re not comfortable replacing the spark plug yourself, consider consulting a professional mechanic or the owner’s manual for guidance. A new spark plug can make a significant difference in the performance and starting ability of your Craftsman lawn mower, so it’s worth taking the time to replace it if necessary.
Can a clogged fuel filter prevent my Craftsman lawn mower from starting?
Yes, a clogged fuel filter can definitely prevent your Craftsman lawn mower from starting. The fuel filter is designed to remove impurities and debris from the fuel, but if it becomes clogged, it can restrict fuel flow to the engine, making it difficult or impossible to start. To check the fuel filter, start by locating it, usually found in the fuel line or attached to the carburetor. Remove the filter and inspect it for any signs of blockage or debris. If the filter is clogged, try cleaning or replacing it, depending on the type and manufacturer’s recommendations.
If you’re unsure how to check or replace the fuel filter, consult the owner’s manual or contact a professional mechanic for assistance. It’s also a good idea to regularly inspect and maintain the fuel filter to prevent clogs and ensure smooth engine operation. A clean fuel filter will help ensure your Craftsman lawn mower runs smoothly, starts easily, and maintains its performance over time. Additionally, a well-maintained fuel filter can also help improve fuel efficiency, reduce emissions, and prolong the lifespan of the engine. By regularly checking and maintaining the fuel filter, you can help prevent startup problems and keep your lawn mower running at its best.
How do I troubleshoot a faulty ignition coil on my Craftsman lawn mower?
If you suspect a faulty ignition coil is preventing your Craftsman lawn mower from starting, start by checking the coil’s condition and connections. Look for any signs of wear, corrosion, or damage on the coil or its connections. Check the coil’s primary and secondary resistance using a multimeter, comparing the readings to the manufacturer’s specifications. If the readings are out of range, it may indicate a faulty coil. Additionally, check the coil’s connections to the spark plug and ignition module, ensuring they’re clean and secure.
If you’ve confirmed the ignition coil is faulty, it’s likely that it needs to be replaced. When replacing the coil, be sure to follow the manufacturer’s instructions and take necessary safety precautions. Start by disconnecting the coil’s connections, then remove the old coil, taking care not to damage any surrounding components. Install the new coil, making sure it’s properly seated and connected, then test the ignition system to ensure it’s functioning correctly. If you’re not comfortable replacing the ignition coil yourself, consider consulting a professional mechanic or the owner’s manual for guidance. A new ignition coil can make a significant difference in the starting ability and performance of your Craftsman lawn mower.
