The warm weather has finally arrived, and your lawn is starting to show its unruly side. You pull out your trusty Craftsman 140cc lawnmower, ready to tackle the task at hand. But then, you realize it’s been a while since you last used it – and you can’t remember how to start it. Don’t worry, you’re not alone! Many people find starting a lawnmower a bit daunting, especially if it’s been sitting idle for a while. This article will guide you through the step-by-step process of starting a Craftsman 140cc lawnmower, covering everything from prepping the mower to troubleshooting common problems.
Starting a Craftsman 140cc lawnmower is a relatively straightforward process, but it does require a few key steps. First, you’ll need to prepare the mower by ensuring it has fuel, oil, and a clean air filter. Then, you’ll need to prime the carburetor and engage the choke. Finally, you’ll pull the starter rope while following the correct techniques to get the engine running smoothly.
Preparing Your Craftsman Lawn Mower
Before you even think about pulling the starter cord, it’s essential to prepare your Craftsman 140cc lawnmower for a successful start. This preparation involves ensuring the mower has enough fuel, oil, and a clean air filter.
Checking Fuel Levels
1. Locate the Fuel Tank: The fuel tank on a Craftsman lawnmower is typically located on the side of the mower deck. Look for a translucent or clear plastic container with a fuel cap.
2. Inspect the Fuel Level: Remove the fuel cap and visually inspect the fuel level. If the fuel level is low, you’ll need to refill the tank.
3. Refill the Tank (If Necessary): Use fresh, clean gasoline with an octane rating of 87 or higher. Do not mix gasoline with oil, as this can damage the engine. Avoid overfilling the tank, as it can lead to fuel spilling during operation.
4. Secure the Fuel Cap: After filling the tank, make sure the fuel cap is securely closed.
Checking Oil Levels
1. Locate the Dipstick: The oil dipstick is usually located on the side of the engine block. It will have a loop or handle at the top for easy removal.
2. Remove the Dipstick: Pull out the dipstick and wipe it clean with a cloth.
3. Insert the Dipstick: Insert the dipstick back into the engine block all the way.
4. Check the Oil Level: Pull the dipstick out again and check the oil level. It should be somewhere between the “Full” and “Add” marks. If the oil level is low, add more oil.
5. Use the Correct Oil: Always use the recommended type of oil for your Craftsman lawnmower. You can find this information in the owner’s manual.
Inspecting the Air Filter
1. Locate the Air Filter: The air filter is typically located inside a black plastic housing on top of the engine.
2. Remove the Air Filter: Open the housing and remove the air filter.
3. Inspect the Air Filter: Look for signs of dirt, debris, or damage. If the filter is dirty or clogged, you’ll need to clean or replace it.
4. Clean or Replace the Air Filter: If the filter is merely dirty, you can clean it by tapping out the dirt or using a brush. If the filter is damaged or severely clogged, you’ll need to replace it with a new one.
5. Reinstall the Air Filter: After cleaning or replacing the air filter, reinstall it in the housing and close it securely.
Starting the Craftsman 140cc Lawn Mower
Once you’ve prepared your Craftsman lawnmower, you can start the engine. Here’s how:
1. Locate the Choke Lever: The choke lever is usually located on the side of the engine. It will have a lever with an arrow that indicates the “Choke” position.
2. Engage the Choke: Move the choke lever to the “Choke” position. This will restrict the airflow to the engine, helping it start more easily.
3. Prime the Carburetor: The carburetor on a Craftsman lawnmower is located near the engine. It has a small primer bulb on the side. Press the primer bulb 3-5 times to fill the carburetor with fuel.
4. Locate the Starter Rope: The starter rope is usually located on the top of the engine. It will have a handle that you pull to start the engine.
5. Pull the Starter Rope: Hold the starter rope handle firmly and pull it sharply. You should feel resistance as you pull.
6. Disengage the Choke: Once the engine starts, slowly move the choke lever back to the “Off” position.
7. Allow the Engine to Warm Up: Let the engine run for a few minutes to warm up before you begin mowing.
Troubleshooting Common Starting Problems
If you’re having trouble starting your Craftsman 140cc lawnmower, it’s often due to a few common issues. Here are some troubleshooting tips:
1. Check the Fuel: If you haven’t used your mower in a while, the fuel in the tank may have gone stale. This can prevent the engine from starting. Drain the old fuel and refill the tank with fresh gasoline.
2. Check the Spark Plug: A faulty spark plug can also prevent the engine from starting. Remove the spark plug, inspect it for damage or carbon buildup, and replace it if necessary.
3. Check the Air Filter: A clogged air filter can restrict airflow to the engine, making it difficult to start. Clean or replace the air filter as needed.
4. Check the Battery (For Electric Start Models): If your Craftsman lawnmower has an electric start, make sure the battery is charged. You can jump-start the battery if it’s low.
5. Check the Ignition System: If you’ve checked all the basics and your mower still won’t start, there might be a problem with the ignition system. You may need to consult a mechanic for help.

FAQ
1. Why won’t my Craftsman 140cc lawn mower start?
There are several reasons why your Craftsman 140cc lawn mower might not start. The most common issues include a dead battery, a clogged air filter, or a fuel problem.
Start by checking the battery. If it’s dead, you’ll need to replace it. If the battery is good, check the air filter. If it’s clogged, clean or replace it. If neither of these is the issue, you may have a problem with the fuel system. Inspect the fuel lines for any blockages and check if the fuel is fresh. If the fuel is old, it may need to be replaced.
2. How do I check the spark plug?
The spark plug is essential for igniting the fuel and starting the engine. To check the spark plug, first disconnect the spark plug wire from the plug. Then, use a socket wrench to remove the spark plug from the engine. Once the spark plug is removed, inspect it for damage or buildup.
If the spark plug is damaged or heavily fouled, it needs to be replaced. If the spark plug looks good, connect the spark plug wire to the plug and hold it near the engine block. Turn the engine over with the ignition key. If there is a spark, the spark plug is working properly. If there is no spark, the problem lies with the ignition system.
3. What if my Craftsman 140cc lawn mower starts but stalls?
If your mower starts but stalls, this can be caused by several factors. A clogged fuel filter, a faulty carburetor, or a lack of fuel can all cause stalling.
First, inspect the fuel filter. If it’s clogged, it needs to be replaced. If the filter is clear, check the carburetor. It may need to be cleaned or adjusted. Lastly, ensure the fuel tank is not empty. If the tank is empty, refill it and try starting the engine again.
4. How do I change the oil in my Craftsman 140cc lawn mower?
Changing the oil regularly is essential for keeping your mower running smoothly. To change the oil, you will need a new oil filter, a drain pan, and the correct type of oil for your mower.
First, warm up the engine for a few minutes. Then, place the drain pan under the oil drain plug and unscrew the plug. Allow the oil to drain completely. Once the oil is drained, replace the drain plug and tighten it securely. Next, remove the old oil filter and install a new one. Finally, add the correct amount of new oil to the engine.
5. How do I adjust the blade height on my Craftsman 140cc lawn mower?
Adjusting the blade height is necessary for achieving the desired lawn length. Most Craftsman 140cc lawn mowers have a lever or knob located near the wheels that controls the blade height.
To adjust the blade height, simply pull the lever or turn the knob to the desired height setting. You can usually find the different height settings marked on the mower’s frame. Ensure that all wheels are set to the same height for even cutting.
6. How often should I service my Craftsman 140cc lawn mower?
Regular servicing is crucial for maintaining the performance and lifespan of your Craftsman 140cc lawn mower. Aim to service your mower at least once per season, or more often if you use it frequently.
This includes tasks like changing the oil, cleaning or replacing the air filter, sharpening the blades, inspecting the fuel lines, and checking the spark plug. Regular servicing will prevent major issues and keep your mower running smoothly for years to come.
7. Where can I find parts for my Craftsman 140cc lawn mower?
