But as you pull your trusty Bolens lawn mower out of storage, you realize you’ve forgotten how to start it. Don’t worry! This comprehensive guide will walk you through the steps of getting your Bolens mower roaring back to life, covering everything from basic troubleshooting to more complex engine issues.
Starting a Bolens lawn mower is a straightforward process, but it requires a few key steps to ensure a smooth and successful start. This article will guide you through the steps for starting a Bolens lawn mower, covering both basic and advanced procedures, including checking fuel levels, priming the carburetor, adjusting the choke, and understanding potential issues that may arise.
Getting Started: Preparation is Key
Before you attempt to start your Bolens mower, take a few minutes to prepare. This will not only ensure a smoother start but also help you identify any potential problems early on.
1. Safety First:
- Always wear safety glasses to protect your eyes from flying debris.
- Check the surrounding area for any obstructions or people who might be injured by the mower.
- Make sure the spark plug wire is disconnected to prevent accidental ignition.
2. Fuel Check:
- Inspect the fuel tank: Make sure it’s at least halfway full with fresh, clean gasoline.
- Check for leaks: If you notice any fuel leaks, address them immediately before starting the mower.
3. Blade Check:
- Ensure the blades are sharp: Dull blades can make mowing difficult and cause uneven cuts. Sharpen or replace them as needed.
- Inspect for damage: Check for any bends or cracks in the blades that might indicate a safety hazard.
The Starting Sequence: Step by Step
Now that you’ve prepared your mower, it’s time to start it up. The following steps are for a typical Bolens lawn mower with a pull-start engine.
1. Prime the Carburetor:
- Locate the primer bulb: This is typically a small, round bulb located near the carburetor.
- Press the bulb several times: This will push fuel into the carburetor, helping the engine start more easily.
2. Set the Choke:
- Find the choke lever: It’s usually located on the side or top of the engine.
- Position the choke lever fully engaged: This restricts airflow to the carburetor, enriching the fuel mixture, and making starting easier.
3. Engage the Ignition:
- Locate the ignition switch: Typically found near the handle, it’s usually a key-like switch or a red button.
- Turn the switch to the “On” position.
4. Pull the Starter Rope:
- Grasp the starter rope firmly: Hold it near the end and pull it out slowly until you feel resistance.
- Pull the rope quickly and forcefully: This will engage the starter mechanism and hopefully get the engine running.
- Don’t over-pull the rope: If the engine doesn’t start after a few pulls, stop and re-prime the carburetor.
5. Disengage the Choke Gradually:
- Once the engine starts: Slowly move the choke lever towards the “Off” position.
- Listen for the engine: If it starts to sputter, return the choke slightly to enrich the fuel mixture again.
Troubleshooting Common Starting Problems:
Sometimes, your Bolens lawn mower might not want to cooperate. Here are some common starting problems and how to address them:
1. No Spark:
- Check the spark plug: Remove it, inspect for damage or fouling, and clean it with a wire brush.
- Test the spark plug: Hold it against a grounded metal surface while pulling the starter rope. If you see a strong spark, the problem lies elsewhere. If not, you might need a new spark plug.
- Inspect the spark plug wire: Make sure it’s securely connected and not damaged.
2. Flooding:
- Symptoms: Black smoke from the exhaust, difficulty starting, and a smell of fuel.
- Solution: Let the engine sit for a few minutes to allow the excess fuel to evaporate. Then, try starting it again, using the steps outlined above.
3. Fuel Problems:
- Bad fuel: Old or contaminated fuel can prevent the engine from starting. Use fresh gasoline and empty the tank if you haven’t used the mower in a while.
- Clogged fuel lines: If the fuel filter is clogged, it will restrict fuel flow to the engine. Replace the filter or clean it thoroughly.
- Carburetor issues: A dirty or malfunctioning carburetor can cause starting problems. Consider cleaning or rebuilding the carburetor if necessary.
Advanced Starting Techniques
If your Bolens mower still refuses to start, you might need to delve deeper. Here are some advanced techniques that could help:
1. Using Starting Fluid (Caution!)
- Only use starting fluid in emergencies: Excessive use can damage the engine.
- Spray a small amount into the carburetor intake while holding the primer bulb down.
- Pull the starter rope immediately: The engine should start with a brief burst of power. If it doesn’t, you may have a more serious issue.
2. Checking the Fuel Pump:
- The fuel pump pushes fuel to the carburetor: If it’s malfunctioning, the engine won’t get enough fuel.
- Listen for a clicking sound: This indicates a working fuel pump.
- Test the fuel pump manually: Disconnect the fuel line from the carburetor and see if fuel flows freely when the pump is activated.
Maintaining Your Bolens Mower: Prevention is Key
Regular maintenance is key to ensuring your Bolens lawn mower starts smoothly and operates efficiently. Here are some essential maintenance tasks:
1. Oil Changes:

3. Spark Plug Maintenance:
- Inspect the spark plug regularly: Check for wear, fouling, or damage.
- Clean the spark plug with a wire brush: This removes dirt and carbon buildup.
- Replace the spark plug if needed: Consult your owner’s manual for the recommended spark plug type and replacement intervals.
4. Blade Sharpening:
- Sharpen the blades regularly: This will improve the quality of your cut and prevent damage to your lawn.
- Use a file or sharpening stone to sharpen the blades.
