The warm sun on your face, the smell of freshly cut grass – there’s nothing quite like a perfectly manicured lawn. But before you can enjoy the fruits of your labor, you need to get your trusty Craftsman lawn mower up and running. If you’re facing a stubborn engine that refuses to cooperate, don’t despair! This comprehensive guide will walk you through the steps to successfully start your Craftsman lawn mower, covering everything from essential checks to troubleshooting common issues.
Starting a Craftsman lawn mower is typically a straightforward process, but it requires a few basic steps. You’ll need to ensure the mower has fuel, the engine is primed, and the spark plug is functioning correctly. Once these elements are in place, you can use the starter to bring the engine to life. However, if your mower refuses to start, it could be due to a multitude of reasons, including a clogged carburetor, a faulty spark plug, or a lack of fuel. This guide will equip you with the knowledge to identify and address these issues, ensuring a smooth and efficient start every time.
Pre-Start Checklist: Essential Preparations
Before attempting to start your Craftsman lawn mower, it’s crucial to conduct a thorough pre-start inspection. This will help identify any potential issues and ensure a safe and efficient start. Here are the essential steps to follow:
1. Fuel Up: Ensuring a Steady Supply
Your Craftsman lawn mower needs fuel to operate, and a low fuel level can be the reason for a stubborn engine. To ensure you have enough fuel, check the fuel tank and refill it if necessary. Make sure to use the correct type of fuel as specified in your owner’s manual. Using the wrong fuel can damage your engine.
2. Inspect the Fuel Lines: Checking for Leaks and Obstructions
Fuel lines are crucial for delivering fuel from the tank to the carburetor. Visually inspect the fuel lines for any signs of leaks, cracks, or blockages. If you notice any issues, it’s best to replace the damaged fuel lines to avoid fuel spills and engine problems.
3. Prime the Engine: A Shot of Fuel for Smooth Ignition
Priming the engine helps provide a small amount of fuel to the carburetor, aiding in ignition. Locate the priming bulb (usually a red or yellow bulb near the carburetor) and press it several times. This will deliver a small amount of fuel to the carburetor, facilitating a smoother start.
4. Inspect the Spark Plug: A Crucial Element for Ignition
The spark plug is responsible for creating the spark that ignites the fuel-air mixture. To ensure proper operation, locate the spark plug and inspect it for wear or damage. If it’s dirty or corroded, it may prevent the engine from starting. Use a spark plug wrench to remove the spark plug and clean it with a wire brush. If the spark plug is damaged, it should be replaced with a new one of the correct type.
5. Check the Battery (For Electric Models): Power Up Your Engine
If your Craftsman lawn mower is electric, check the battery to ensure it’s fully charged. A weak battery can prevent the engine from starting. Make sure the battery terminals are clean and secure to ensure proper electrical connection.
Starting Your Craftsman Lawn Mower: Step-by-Step
Now that you’ve completed the pre-start inspection, it’s time to start your Craftsman lawn mower. Follow these steps for a smooth and successful start:
1. Engage the Choke: Enriching the Fuel Mixture
The choke controls the amount of air entering the engine, enriching the fuel-air mixture. To start a cold engine, engage the choke. This will provide a richer mixture that ignites more easily. You can usually find the choke lever near the handlebars.
2. Pull the Starter Cord: Giving Your Engine the First Push
Pull the starter cord slowly at first, then give it a quick, firm pull to start the engine. Avoid pulling the cord all the way out, as this can damage the recoil mechanism.
3. Disengage the Choke: Adjusting for a Smooth Running Engine
Once the engine is running, disengage the choke gradually. This will allow the engine to run at its normal speed and prevent stalling.
4. Check for Smooth Engine Operation: Ensuring Proper Performance
Listen for any unusual noises, vibrations, or smoke coming from the engine. If the engine is running smoothly, you can begin mowing your lawn.

FAQ
1. Why won’t my Craftsman lawn mower start?
There are a few common reasons why your Craftsman lawn mower might not start. First, check if you have fresh gasoline in the tank. Old gasoline can go bad and prevent your mower from starting. Second, ensure the spark plug is properly connected and has a good spark. You can test this by holding the spark plug wire near the engine block and seeing if a spark jumps. Lastly, make sure the air filter is clean. A clogged air filter can restrict airflow and prevent the engine from starting.
If you have checked all of these things and your mower still won’t start, you might need to have it serviced by a professional. They can diagnose any underlying problems and make necessary repairs.
2. How do I change the oil in my Craftsman lawn mower?
Changing the oil in your Craftsman lawn mower is a simple maintenance task that helps prolong the life of your engine. First, let the engine cool completely. Then, locate the oil drain plug and place a drain pan underneath it. Unscrew the plug and let the oil drain completely. Once the oil has drained, replace the drain plug and tighten it securely.
Next, remove the oil fill cap and pour in the correct amount of oil specified in your owner’s manual. Make sure to use the correct type of oil for your mower. Finally, replace the oil fill cap and start the engine briefly to ensure the oil is circulating properly.
3. What kind of gas should I use for my Craftsman lawn mower?
Always use unleaded gasoline with an octane rating of 87 or higher in your Craftsman lawn mower. Avoid using gasoline that is more than 30 days old, as it can degrade and cause engine problems.
