The warm weather is finally here, and you’re ready to tackle your lawn. But when you go to fire up your trusty Craftsman 6.25 lawn mower, it sputters and refuses to start. Frustration sets in, and you wonder if you need to call a mechanic. Don’t worry! This guide will equip you with the knowledge and steps needed to get your Craftsman 6.25 lawn mower running smoothly again. We’ll cover everything from basic troubleshooting tips to more advanced techniques for tackling common starting issues.
A Quick Overview
Most Craftsman 6.25 lawn mowers are equipped with a Briggs & Stratton engine. These engines are known for their reliability, but they can occasionally experience starting problems. Common issues include a lack of fuel, a clogged air filter, a faulty spark plug, or a dead battery (if you have an electric start model). This article will guide you through diagnosing and addressing these problems step-by-step.
Diagnosing the Problem
The first step to getting your Craftsman 6.25 lawn mower running is to identify the underlying issue. Here’s a quick checklist to help you narrow down the possibilities:
1. Fuel: Is the gas tank empty? Is the fuel old and stale?
2. Air Filter: Is the air filter dirty or clogged?
3. Spark Plug: Is the spark plug corroded or fouled?
4. Battery: If you have an electric start model, is the battery charged?
5. Engine Choke: Is the choke properly set?
Once you’ve checked these items, you can start to tackle the problem.
Troubleshooting Fuel Issues
1. Check the Fuel Tank
The first and most obvious thing to check is whether your lawn mower has fuel.
- Open the fuel cap: If the tank is empty, simply refill it with fresh gasoline.
- Check the fuel level: Even if the tank isn’t empty, check the fuel level. If the fuel is low, you may need to add more.
- Inspect the fuel line: Look for any cracks or leaks in the fuel line.
- Clean the fuel line: If the fuel line looks dirty or clogged, you may need to clean it with a wire brush or compressed air.
2. Replace Old Fuel
If the fuel in your tank is old, it can become stale and gum up your engine.
- Drain the old fuel: Use a siphon pump or a clean container to remove the old fuel from the tank.
- Refill with fresh fuel: Add fresh, high-octane gasoline to the tank.
3. Clean the Fuel Filter
A clogged fuel filter can prevent fuel from reaching the engine.
- Locate the fuel filter: The fuel filter is usually located near the fuel tank or carburetor.
- Remove the filter: Carefully remove the fuel filter from the line.
- Inspect the filter: Check the filter for dirt, debris, or other blockages.
- Clean the filter: If the filter is dirty, you can try to clean it with a wire brush or compressed air.
- Replace the filter: If the filter is too damaged or clogged, replace it with a new one.
Troubleshooting Air Filter Issues
A clogged air filter can restrict airflow to the engine, making it difficult to start.
1. Locate and Remove the Air Filter
The air filter is typically located under a plastic cover on the top or side of the engine.
2. Inspect the Air Filter
- Check for dirt and debris: If the filter is dirty or clogged, replace it with a new one.
- Clean the air filter: If the filter is washable, you can remove it and clean it with soap and water. Allow it to dry completely before reinstalling it.
Troubleshooting Spark Plug Issues
A faulty spark plug can prevent the engine from firing.
1. Locate and Remove the Spark Plug
The spark plug is located on the top of the engine, near the air filter. Use a spark plug wrench to remove the spark plug.
2. Inspect the Spark Plug
- Check for corrosion and fouling: A corroded or fouled spark plug can prevent a spark from firing.
- Check the gap: The spark plug gap should be between 0.025 and 0.030 inches. You can use a gap gauge to check the spark plug gap.
- Check the electrode: The electrode should be clean and free of debris.
3. Replace or Clean the Spark Plug
- Replace: If the spark plug is damaged, corroded, or fouled, replace it with a new one.
- Clean: If the spark plug is simply dirty, you can clean it with a wire brush or a spark plug cleaning tool.
Troubleshooting Battery Issues (For Electric Start Models)
If your Craftsman 6.25 lawn mower has an electric start, a dead battery can prevent the engine from starting.
1. Check the Battery Terminals
- Clean the terminals: If the battery terminals are corroded, clean them with a wire brush or a battery terminal cleaner.
- Check for loose connections: If the battery terminals are loose, tighten them with a wrench.
2. Test the Battery
- Use a multimeter: A multimeter can be used to test the battery voltage. A fully charged battery should have a voltage of 12.6 volts.
- Jump start the battery: If the battery is dead, you can try to jump start it with another battery.
3. Replace the Battery
If the battery is dead or too old, replace it with a new one.
Starting Your Craftsman 6.25 Lawn Mower
Once you’ve addressed any potential issues, you can start your Craftsman 6.25 lawn mower.
1. Set the Choke
- Cold start: If the engine is cold, set the choke to the “choke” position.
- Warm start: If the engine is warm, you can set the choke to the “run” position.
2. Prime the Engine (If Applicable)
Some Craftsman 6.25 lawn mowers have a primer bulb. If yours does, press the primer bulb several times to fill the carburetor with fuel.
3. Pull the Starter Cord
- Grasp the cord: Grasp the starter cord firmly near the handle.
- Pull the cord slowly: Pull the cord slowly until you feel resistance.
- Pull the cord quickly: Once you feel resistance, pull the cord quickly and forcefully.
- Continue pulling: Continue pulling the cord until the engine starts.
4. Adjust the Choke
Once the engine is running, slowly adjust the choke to the “run” position.
5. Let the Engine Warm Up
Allow the engine to warm up for a few minutes before you begin mowing.

Frequently Asked Questions
1. What are the key things I need to do before starting my Craftsman 6.25 lawn mower?
Before you start your Craftsman 6.25 lawn mower, it’s crucial to ensure it’s in good working order and that you have a safe environment. Begin by checking the fuel level and adding fuel if necessary. Then, check the oil level and add oil if needed. It’s essential to use the correct type of oil recommended by your mower’s manual. Also, check the air filter to ensure it’s clean and replace it if it’s dirty. This will help the engine run smoothly and efficiently.
Finally, inspect the spark plug for signs of wear or damage. If it’s damaged, replace it. A clean spark plug is crucial for starting the engine. It’s also important to ensure the blade is securely attached and sharp. A dull blade will not cut efficiently and can be dangerous. Remember to always work in a well-ventilated area, and wear safety goggles and gloves while working with your mower.
2. What are the steps to starting a Craftsman 6.25 lawn mower?
Starting a Craftsman 6.25 lawn mower is fairly straightforward. First, make sure the choke is engaged. This will help enrich the fuel mixture and make starting easier. Next, turn the fuel valve to the “ON” position. Then, hold the mower firmly on the ground and pull the starter cord slowly until you feel resistance. Then pull the cord quickly and forcefully. If the engine doesn’t start, try these steps again, ensuring the choke is engaged.
If the engine still doesn’t start, check if the fuel tank is empty or if the fuel line is blocked. Once the engine starts, disengage the choke gradually and let the engine run for a few minutes to warm up. During this time, you can adjust the engine speed to the desired level. Once warmed up, the engine should be ready for mowing. Remember to always follow the safety instructions in your owner’s manual.
3. What if my Craftsman 6.25 lawn mower won’t start?
If your Craftsman 6.25 lawn mower won’t start, there are a few things you can check. First, verify that there’s fuel in the tank and that the fuel valve is turned to the “ON” position. Next, check the spark plug to make sure it’s clean and properly connected. If the spark plug is fouled or damaged, it needs to be replaced. Also, check the air filter to make sure it’s clean. A dirty air filter can restrict airflow and prevent the engine from starting.
Finally, ensure that the blade is not obstructed and can rotate freely. If none of these solutions work, you may need to consult your owner’s manual or contact a qualified repair person. Always exercise caution and follow safety guidelines while working on your lawn mower.
