The warm weather has arrived, and your lawn is calling for a trim. But there’s a problem: you haven’t started your lawnmower all season, and you’re not quite sure how. Don’t worry, starting a lawn mower with a pull cord can seem daunting, but it’s actually quite simple. In this comprehensive guide, we’ll walk you through the process step-by-step, covering everything from preparing your mower to troubleshooting common issues. By the end of this article, you’ll be a lawn-mowing pro!
Starting a lawnmower with a pull cord is a fundamental skill for any homeowner. It involves a sequence of actions that prime the engine, provide fuel, and ignite the spark plug. The process involves understanding the different parts of the mower and performing them in the correct order. Let’s get started!
Getting Ready: Preparing Your Lawn Mower
Before you even touch the pull cord, it’s crucial to ensure your lawnmower is in good working condition and prepared for a successful start. Here’s what you need to do:
1. Check the Fuel Level
The first step is to check the fuel level. Your lawnmower likely runs on gasoline, and a low fuel level will prevent the engine from starting. Locate the fuel tank, typically found on the side of the mower, and check the gauge or the fuel level through the tank’s clear window. If the fuel level is low, you’ll need to refill the tank.
Important Note: Avoid overfilling the fuel tank. Always leave some space for expansion to prevent spills or overflows.
2. Inspect the Spark Plug
The spark plug is a critical component that ignites the fuel-air mixture in the engine. A dirty or damaged spark plug can cause starting problems.
How to Inspect the Spark Plug:
- Locate the spark plug on the engine’s top.
- Disconnect the spark plug wire (the black wire connected to the spark plug).
- Remove the spark plug using a spark plug socket wrench.
- Examine the spark plug for signs of wear, damage, or excessive carbon buildup.
How to Clean the Spark Plug:
- If the spark plug is dirty, use a wire brush to clean it.
- Ensure the gap between the electrode tips is correct. Refer to the owner’s manual for the proper gap measurement.
Important Note: If the spark plug is damaged, replace it with a new one.
3. Inspect the Air Filter
The air filter protects the engine from dirt and debris. A clogged air filter can restrict airflow and hinder starting.
How to Inspect and Clean the Air Filter:
- Locate the air filter housing, often found near the engine.
- Remove the air filter cover.
- Remove the air filter element.
- If it’s dirty, use a vacuum cleaner or compressed air to blow out any dust or debris.
Important Note: Replace the air filter if it is excessively dirty or damaged.
The Pull-Start Process
Now that your lawnmower is prepped, it’s time to start the engine:
1. Prime the Engine
Most lawnmowers have a primer bulb, which allows you to manually inject fuel into the carburetor. This helps to ensure a good fuel mixture for easier starting.
How to Prime the Engine:
- Locate the primer bulb, usually found near the carburetor.
- Depress the primer bulb several times (refer to your owner’s manual for the recommended number of presses). This will deliver fuel to the carburetor.
2. Set the Choke
The choke restricts airflow to the carburetor, enriching the fuel mixture for easier starting, especially when the engine is cold.
How to Set the Choke:
- Locate the choke lever, usually located on the handle of the lawnmower.
- Move the choke lever to the “choke” position. This is often indicated by a symbol or a “choke” label.
3. Pull the Cord
Now it’s time to pull the cord. This is the most important step, and it requires a little bit of technique.
How to Pull the Cord:
- Locate the recoil starter handle, usually located near the engine.
- Grasp the handle firmly.
- Pull the cord slowly until you feel resistance.
- Then, quickly and decisively pull the cord all the way out.
- Be prepared for a kickback – a sudden recoil of the cord.
Tips for Pulling the Cord:
- Use the Proper Grip: Hold the handle firmly and avoid using your thumb.
- Avoid Jerking: Don’t jerk the cord. Pull it smoothly and quickly.
- Don’t Over-Pull: If the cord comes out all the way without starting the engine, pull it out again. Excessive pulling can damage the starter mechanism.
4. Adjust the Choke
Once the engine starts, you can start to adjust the choke.
How to Adjust the Choke:
- Gradually move the choke lever to the “run” position, This will gradually reduce the fuel richness and allow the engine to warm up.
Troubleshooting Common Starting Issues
Even with the right steps, your lawnmower might still not start. Here’s what to do if you encounter common starting problems:
1. Engine Won’t Turn Over
If the engine doesn’t turn over at all when you pull the cord, there could be a few reasons:
- Dead Battery: If your mower has an electric starter, a dead battery could be the culprit.
- Clogged Air Filter: A clogged air filter can prevent enough air from reaching the engine, preventing it from starting.
- Flooded Engine: If the engine has been flooded with too much fuel, it won’t start.
How to Fix:
- Check the Battery: If you have an electric starter, check the battery’s connection and charge.
- Clean the Air Filter: Ensure the air filter is clean and allows air to flow freely.
- Clear the Flooded Engine: Remove the spark plug and crank the engine to expel excess fuel.
2. Engine Starts But Dies
If the engine starts but immediately dies, this is another common starting problem. Here are a few reasons:
- Fuel Problems: The fuel could be old or stale, or the carburetor might be dirty.
- Spark Plug Problems: A faulty spark plug can prevent the engine from running smoothly.
How to Fix:
- Replace Old Fuel: If the fuel is old, drain the fuel tank and refill it with fresh gasoline.
- Clean the Carburetor: If you suspect a dirty carburetor, clean it using a carburetor cleaner.
- Inspect the Spark Plug: Check the spark plug for wear and tear and replace it if necessary.
