Understanding the Basics: Pre-Start Checks
Before you even think about pulling that starter cord, it’s essential to perform some pre-start checks to ensure your mower is ready to go. These checks will help identify potential problems and prevent unnecessary frustration.
1. Fuel Level and Quality:
- Fuel Level: Check the fuel tank and make sure it’s filled with fresh gasoline. Old or stale gas can cause starting issues.
- Fuel Quality: Always use fresh, clean gasoline that meets the specifications outlined in your owner’s manual. Typically, you’ll want to use 87 octane unleaded gasoline.
2. Oil Level:
- Check the Oil: Your Craftsman mower requires a specific type and amount of oil. Consult your owner’s manual for the recommended oil and check the dipstick to ensure the oil level is within the appropriate range.
3. Air Filter:
- Clean or Replace: A dirty air filter restricts airflow to the engine, hindering its ability to start. Clean or replace the air filter as needed.
4. Spark Plug:
- Inspect the Spark Plug: A faulty spark plug can prevent your mower from starting. Inspect the spark plug for wear or damage. If it’s worn or damaged, replace it with a new one.
5. Blade Sharpness:
- Sharp Blades: Dull blades can damage your lawn and make it difficult to cut grass effectively. Ensure your blades are sharp before starting the mower.
Priming the Engine: Getting Ready to Start
Once you’ve performed the pre-start checks, it’s time to prime the engine. This step ensures that there’s enough fuel in the carburetor to initiate combustion.
1. Locate the Primer Bulb:
- Identify the Primer Bulb: The primer bulb is usually a small, rubber bulb located near the carburetor.
2. Prime the Engine:
- Pump the Bulb: Gently pump the primer bulb 4-5 times to introduce fuel into the carburetor.
3. Allow Time to Prime:
- Wait a Few Seconds: Let the fuel flow through the carburetor for a few seconds before attempting to start the mower.
Starting Your Craftsman Lawn Mower: The Final Steps
With the engine primed and ready to go, you can now attempt to start your Craftsman lawn mower. Follow these steps carefully:
1. Engage the Choke:
- Set the Choke: The choke lever restricts airflow, making it easier to start a cold engine. Engage the choke lever by moving it to the “choke” position.
2. Pull the Starter Cord:
- Pull Firmly: Grasp the starter cord firmly and pull it back swiftly and smoothly.
- Multiple Pulls: You may need to pull the starter cord several times before the engine starts.
3. Disengage the Choke:
- Once the Engine Starts: Once the engine starts, immediately disengage the choke lever by moving it to the “run” position.
4. Let the Engine Warm Up:
- Allow Time for Warm-Up: Let the engine run for a few minutes before mowing to allow it to reach its optimal operating temperature.
Common Starting Problems and Troubleshooting Tips
Even with careful preparation, you might encounter starting problems with your Craftsman lawn mower. Here are some common issues and solutions:
1. The Mower Won’t Start at All:

FAQ
Q1: My Craftsman mower won’t start. What should I do?
The most common reasons for a Craftsman mower not starting are lack of fuel, a dead battery, or a clogged air filter. First, check the fuel tank to ensure there is fuel. If the tank is empty, fill it up and try starting the mower again. If it still doesn’t start, check the battery terminals for corrosion and clean them with a wire brush. If the battery is dead, you will need to jump-start it or replace it. Lastly, inspect the air filter for dirt and debris. A clogged air filter can restrict airflow to the engine and prevent it from starting.
If the fuel, battery, and air filter are in good condition, you might have an issue with the spark plug or the carburetor. Inspect the spark plug for wear and tear and replace it if necessary. If the spark plug is fine, then the carburetor may be clogged or need adjustment. You can try cleaning the carburetor yourself or taking it to a professional mechanic for repair.
Q2: How do I know if my Craftsman lawn mower needs a tune-up?
Knowing when your Craftsman lawn mower needs a tune-up is crucial for its longevity and performance. The signs that your mower needs a tune-up include difficulty starting, uneven cutting, excessive smoke, and decreased power. If you notice any of these signs, it’s time to take your mower in for a professional tune-up. This usually involves cleaning or replacing the air filter, spark plug, and fuel filter, as well as adjusting the engine speed and the carburetor.
A regular tune-up will help to improve your mower’s fuel efficiency, reduce emissions, and extend its lifespan. It’s best to get your mower tuned up once a year, especially before the start of mowing season.
Q3: Can I use any type of fuel in my Craftsman mower?
While your Craftsman lawn mower may seem like a simple machine, using the wrong fuel can lead to major problems. You should always use gasoline that is specifically designed for lawn mowers. This fuel is typically labeled as “gasoline with ethanol” and should be 87 octane or higher. Avoid using fuel that is intended for cars or other vehicles, as it may contain additives that can damage your mower’s engine.
Additionally, never mix gasoline with oil, as this can lead to serious engine damage. Always use the recommended oil for your Craftsman mower, which can be found in the owner’s manual.
Q4: How often should I change the oil in my Craftsman lawn mower?
Changing the oil in your Craftsman lawn mower regularly is essential for maintaining its performance and longevity. The frequency of oil changes depends on the type of oil used and the usage of the mower. Typically, you should change the oil every 25 hours of operation or at the start of each mowing season.
When changing the oil, be sure to use the correct type and grade of oil as recommended in your owner’s manual. You should also check the oil filter and replace it if it is dirty or worn.
Q5: What is the proper way to dispose of old gasoline?
Disposing of old gasoline is a crucial aspect of owning a Craftsman lawn mower. Never pour gasoline down the drain or into the ground, as this can contaminate the environment. Instead, you can use a gasoline disposal container or take it to a local recycling center.
You can also use up the remaining gasoline in your Craftsman mower by using it for other tasks around your property, such as operating a generator or powering a small engine. If you need to dispose of a large amount of gasoline, consider contacting a professional hazardous waste disposal company.
Q6: How do I safely store my Craftsman lawn mower for the winter?
Storing your Craftsman lawn mower properly during the winter is crucial for preventing damage and ensuring a smooth start next season. First, drain the gas tank to prevent any fuel from deteriorating or becoming contaminated. Then, clean the mower thoroughly, removing any dirt, grass, or debris. Once clean, it’s best to store the mower in a dry, sheltered location, such as a garage or shed.
Additionally, consider adding a fuel stabilizer to the remaining gasoline in the tank before storing the mower. This will help to prevent fuel from breaking down and damaging the engine. Finally, remove the spark plug wire before storing the mower to prevent accidental starting.
Q7: My Craftsman mower is making a strange noise. What could be wrong?
Strange noises from your Craftsman lawn mower can be a sign of various issues. A loud rattling noise could indicate a loose blade, a worn-out bearing, or a problem with the engine. A high-pitched whine could suggest a problem with the transmission or the drive belt. A grinding noise could indicate a worn-out clutch or a problem with the blades.
If you hear any strange noises, it is important to stop using your mower immediately and have it inspected by a professional mechanic. Ignoring these noises can lead to more serious problems and potentially costly repairs in the future.
