The warm weather has arrived, and with it comes the desire to have a beautiful, green lawn. But before you can enjoy a perfectly manicured yard, you need a working lawnmower. And if you own a pull-start mower, you’ll need to know how to get it going. This guide will walk you through the process step-by-step, ensuring you can conquer even the toughest lawn with ease.
A Quick Overview
Pulling the starter rope on a lawnmower is a simple process. It involves engaging the engine’s flywheel to turn the crankshaft and ignite the spark plug. However, there are a few crucial things to keep in mind to ensure a smooth start and avoid damage to your mower. This article will cover essential steps, troubleshooting tips, and safety precautions to help you master the art of pull-starting your lawnmower.
Preparing Your Lawn Mower for Starting
Before you even think about pulling the starter rope, it’s essential to ensure your lawnmower is in optimal condition. Here’s a quick checklist:
1. Check the Fuel Level:
- Importance: A lack of fuel will obviously prevent your mower from starting.
- Procedure: Check the fuel tank level. If it’s low, add fresh, clean gasoline.
- Note: Use the recommended fuel type as specified in your mower’s manual.
2. Inspect the Spark Plug:
- Importance: A faulty spark plug will prevent the engine from igniting.
- Procedure:
- Locate the spark plug, usually found on the engine’s side.
- Use a spark plug wrench to loosen and remove the plug.
- Inspect the plug for signs of wear, damage, or carbon buildup.
- Clean the plug with a wire brush if necessary.
- Replace the plug if it’s damaged or excessively worn.
- Note: Ensure the spark plug gap is set correctly according to the manufacturer’s specifications.
3. Examine the Air Filter:
- Importance: A clogged air filter restricts airflow to the engine, hindering its ability to start.
- Procedure:
- Locate the air filter, usually found near the carburetor.
- Remove the filter and inspect it for dirt or debris.
- If it’s dirty, clean it with a brush or replace it with a new one.
4. Inspect the Fuel Line:
- Importance: A clogged fuel line will prevent fuel from reaching the carburetor.
- Procedure:
- Look for any cracks, leaks, or blockages in the fuel line.
- If necessary, replace the fuel line.
5. Check the Oil Level:
- Importance: Low oil levels can lead to engine damage.
- Procedure:
- Locate the oil dipstick, usually found on the side of the engine.
- Wipe the dipstick clean and insert it back into the dipstick tube.
- Remove the dipstick and check the oil level.
- Add oil if it’s below the “Full” mark.
- Note: Use the recommended type of oil for your mower, and avoid overfilling.
The Art of Pulling the Starter Rope
Now that your mower is prepped, it’s time to pull that rope! Here’s how to do it safely and effectively:
1. Position the Mower:
- Safety First: Ensure the mower is on a flat, stable surface.
- Clear the Area: Clear any obstacles that could be in the way of the starter rope.
- Engage the Blade Clutch: Make sure the blade clutch lever is disengaged to prevent accidental blade engagement.
2. Choke the Engine:
- Importance: Choking the engine provides a richer fuel-air mixture for easier starting, particularly when cold.
- Procedure:
- Locate the choke lever (usually a lever or knob near the carburetor).
- Engage the choke lever fully.
3. Prime the Carburetor (If Necessary):
- Importance: Priming the carburetor helps supply the engine with fuel for a smoother start, especially if the mower has been sitting for a while.
- Procedure:
- Locate the primer bulb (often a red bulb near the carburetor).
- Pump the bulb a few times until it becomes firm.
4. Pull the Starter Rope:
- Safety First: Avoid wrapping your hand around the starter rope to prevent injury if it recoils.
- Pulling Technique:
- Hold the starter rope handle firmly with your hand.
- Slowly pull the rope out, feeling for resistance.
- Once you feel resistance, pull the rope quickly and forcefully.
- Release the rope slowly to allow it to rewind.
5. Repeat if Needed:
- Importance: It may take a few pulls to start the engine, especially if the mower is cold or hasn’t been used in a while.
- Persistence: Continue pulling the starter rope until the engine fires.
6. Disengage the Choke:
- Importance: Once the engine is running, disengage the choke to allow the engine to run smoothly.
- Procedure: Slowly move the choke lever back to its disengaged position.
7. Let the Engine Warm Up:
- Importance: Allow the engine to run for a few minutes to reach operating temperature.
- Warm-Up: Run the mower at a low idle speed for a couple of minutes before engaging the blade.

FAQ
What is a pull start?
A pull start is a manual method used to start a small gasoline engine, commonly found in lawnmowers, generators, and other small engines. It consists of a rope attached to a spring-loaded mechanism that engages the engine’s crankshaft, initiating the combustion cycle. Pulling the rope quickly and forcefully rotates the crankshaft, allowing the engine to draw in fuel and air, ignite it, and start running.
Why would I need to pull start a lawnmower?
You might need to pull start a lawnmower if its electric starter is malfunctioning, the battery is dead, or if your mower doesn’t have an electric start option at all. Pull starting is a reliable alternative when the electric starter isn’t available or working properly. It’s a simple and effective way to get your mower running without relying on electronic components.
What should I do before pulling the starter rope?
Before you start pulling, ensure that the mower is in a stable position on a flat surface. Make sure the spark plug wire is connected and the fuel tank has enough fuel. Engage the blade brake to prevent accidental movement. You can also check the oil level to ensure your engine is well-lubricated. Finally, make sure the choke is in the correct position for starting the engine.
How do I properly pull the starter rope?
To pull the starter rope, first, you need to gently pull it out a few inches to remove any slack. Then, grasp the rope firmly with your dominant hand and position your other hand on the mower handle for stability. With a strong, quick motion, pull the rope all the way out. Be careful not to let the rope go as it recoils back into the starter housing.
What if the lawnmower won’t start after a few pulls?
If the lawnmower doesn’t start after a few pulls, there could be several reasons. Check the fuel level and ensure the spark plug is clean and properly connected. Also, ensure the choke is in the correct position and the air filter isn’t clogged. If these are all fine, you might have a spark plug issue or a problem with the carburetor. It’s a good idea to consult a mechanic if you cannot identify the issue.
What if the pull start rope breaks?
If the pull start rope breaks, you’ll need to replace it. Disconnect the spark plug wire to prevent accidental starting. Remove the housing that holds the rope and spring mechanism. Carefully detach the old rope and install the new one, ensuring it is securely attached to the spring mechanism. Reassemble the housing and reconnect the spark plug wire.
Is there anything else I should know about pull starting?
Always wear safety glasses and gloves when pulling the starter rope. Be cautious of the blade and ensure it’s stopped before you begin pulling. Also, be aware of the recoil force as you pull the rope. It can be quite strong and may lead to injuries if not handled properly. If you are unsure about any part of the process, it’s best to consult a mechanic or refer to your lawnmower’s user manual.
