Starting a Craftsman Briggs & Stratton Lawn Mower: A Quick Overview
Starting a Craftsman Briggs & Stratton lawn mower typically involves a few simple steps:
- Prepare the mower: This includes ensuring the mower is on a level surface, checking the fuel level, and inspecting the spark plug.
- Prime the engine: This step involves manually feeding fuel into the carburetor to help the engine start.
- Engage the choke: This helps enrich the fuel-air mixture, making it easier to start a cold engine.
- Pull the starter cord: This will crank the engine and hopefully ignite the fuel.
- Disengage the choke once the engine is running: This allows the engine to run at its optimal speed.
However, each mower model and engine might have slight variations, and some models might require additional steps.
Understanding Your Craftsman Briggs & Stratton Mower
Before attempting to start your mower, it’s crucial to understand your specific model and its features. Take some time to read the user manual that came with your mower. This will provide you with detailed instructions on how to operate, maintain, and troubleshoot your specific model.
Pre-Start Checks: Setting the Stage for a Smooth Start
- Fuel Level: Check the fuel tank level. If it’s low, refill it with fresh gasoline. Avoid using old or stale gasoline, as it can cause engine problems.
- Spark Plug: Inspect the spark plug for signs of wear or corrosion. A clean and properly gapped spark plug is essential for reliable ignition.
- Oil Level: Check the oil level in the crankcase. Ensure it’s within the recommended range.
- Blade Condition: Inspect the blades for sharpness and damage. Dull or damaged blades can create an uneven cut and affect the performance of your mower.
- Safety Equipment: Wear safety glasses, sturdy shoes, and hearing protection. Always operate the mower in a well-ventilated area, away from flammable materials.
- Level Surface: Ensure the mower is on a level surface. This helps prevent the mower from tipping over or straining the engine.
Starting the Engine: The Key to Bringing Your Mower to Life
- Prime the Engine: Locate the primer bulb on the carburetor. This is usually a small red bulb. Press the primer bulb several times to fill the carburetor with fuel. This step is crucial, especially if you’re starting the mower for the first time or after a period of inactivity.
- Engage the Choke: Look for the choke lever on the mower. It’s usually located near the handle. Engage the choke by moving the lever to the “choke” position. This restricts airflow, allowing for a richer fuel-air mixture that’s easier to ignite in a cold engine.
- Pull the Starter Cord: Locate the starter cord, which is usually a red rope or handle attached to the engine. Hold the handle firmly and pull it slowly until you feel resistance, then pull it quickly and forcefully. Do not yank the cord as it can damage the engine.
- Disengage the Choke: Once the engine starts, gradually disengage the choke by moving the lever to the “run” position. This will allow the engine to run at its optimal speed.
Troubleshooting Starting Issues: When Things Don’t Go as Planned
Sometimes, starting a lawn mower can be a bit challenging. Here are a few common problems and solutions:
- Mower Won’t Start:
- Check Fuel Line: Make sure the fuel line is connected properly and not kinked or clogged.
- Clean the Air Filter: A dirty air filter can restrict airflow and prevent the engine from starting. Remove and clean the air filter.
- Inspect the Spark Plug: Make sure the spark plug is clean and has the correct gap. You can use a spark plug wrench to remove and clean the spark plug. If the plug is worn, replace it with a new one.
- Engine Starts But Dies Immediately:
- Fuel Shortage: If the engine dies shortly after starting, it may be due to a fuel shortage. Check the fuel level and ensure the fuel line is not clogged.
- Clogged Fuel Filter: A clogged fuel filter can restrict fuel flow and cause the engine to stall. Replace the fuel filter if it’s dirty.
- Engine Runs Rough:
- Dirty Carburetor: A dirty carburetor can cause the engine to run rough or stall. Clean the carburetor thoroughly with a carburetor cleaner.
- Old or Stale Gasoline: Old gasoline can leave deposits in the carburetor and cause engine problems. Drain the old fuel and refill the tank with fresh gasoline.
Safety Precautions: Always Prioritize Safety
Always remember to prioritize safety when operating your lawn mower.
- Always wear safety glasses and sturdy shoes: This will protect your eyes and feet from debris and potential injuries.
- Never operate the mower on uneven or slippery surfaces: This can cause the mower to tip over.
- Never operate the mower in wet conditions: This can create a shock hazard and make it difficult to control the mower.
- Always stop the engine before refueling: This will prevent accidental fires.
- Keep children and pets away from the operating area: This will prevent accidents.

FAQs
How do I know if my Briggs & Stratton engine has a choke?
Many Briggs & Stratton engines, particularly older models, have a choke. You can easily identify it by its lever located on the engine. It typically has a red or yellow color and might be marked with the word “CHOKE.” However, if you can’t find a lever labeled “CHOKE,” your engine might not have one. Modern engines with electronic ignition systems often don’t require a choke.
If you’re still unsure, consult your owner’s manual. It will provide a clear indication of whether or not your engine has a choke. You can also find information about your specific model online, including diagrams and descriptions.
Why is my lawnmower not starting?
Several reasons can cause your Briggs & Stratton lawnmower to refuse to start. First, ensure the fuel tank has fresh gasoline. Old gas can gum up the carburetor. Then, check if the spark plug is properly connected and has a good spark. A faulty spark plug can prevent the engine from igniting. Additionally, ensure the air filter is clean; a clogged air filter restricts airflow and hinders combustion.
If all these components are in order, the problem might be related to the carburetor. A dirty or malfunctioning carburetor can prevent fuel from reaching the engine. You may need to clean the carburetor or replace it. Finally, check the battery connection if your lawnmower is battery-powered. A weak or faulty battery can prevent the engine from starting.
