If you’ve recently acquired a Craftsman lawn mower or simply want to sharpen your maintenance skills, knowing how to start it reliably is essential. Whether you’re prepping for the first mow of the season or reviving your mower after some downtime, getting the process right saves time and keeps your equipment running smoothly. This guide walks you through preparing, starting, troubleshooting, and maintaining your Craftsman lawn mower, so you can enjoy hassle-free mowing all year long.
Preparing Your Craftsman Lawn Mower For Starting
Checking The Fuel And Oil Levels
Before you even think about pulling the starter cord, make sure your mower has the right amount of fuel and oil. Craftsman mowers typically run on unleaded gasoline with an octane rating of 87 or higher, but avoid gasoline blends with more than 10% ethanol as they can harm the engine over time. Always fill the tank when the engine is cool to prevent fuel expansion issues.
For oil, refer to your mower’s manual to know the correct grade, but SAE 30 is common for warmer months. Use the dipstick to check levels, too little oil can cause engine damage, and overfilling can lead to poor performance. Top off or change the oil regularly for the best results.
Inspecting The Air Filter And Spark Plug
A clean air filter ensures your engine breathes well and runs efficiently. Before starting, check if the air filter is clogged with dirt or debris. If it looks dirty or hasn’t been replaced in a season, swap it out. This simple step can prevent hard starting and loss of power.
Next, inspect the spark plug. Remove it and look for signs of wear, corrosion, or a dirty electrode. A fouled spark plug can cause misfires or no spark at all. Clean gently with a wire brush or replace it if it’s damaged. Ensuring a strong spark is key to a smooth start.
Safety Precautions Before Starting
Never overlook safety. Make sure the lawn mower is on a flat surface, away from obstacles. Remove any objects from the mowing deck area to prevent flying debris. Keep hands and feet clear of the blades and never start the mower indoors or in enclosed spaces to avoid exhaust hazards. Wearing protective gloves and safety glasses is a good practice too.
Starting Your Craftsman Lawn Mower Step-By-Step
Priming The Engine Properly
Many Craftsman models feature a primer bulb that needs to be pressed several times before starting, which floods the carburetor with fuel for easier ignition. Typically, press the primer bulb 3 to 5 times firmly but without forcing it. Avoid over-priming, as that can flood the engine and make starting harder.
Setting The Throttle And Choke Controls
Adjust the choke to the “full choke” or “start” position when starting a cold engine. If your mower has a throttle lever, set it to a midway or “fast” position to help the engine turn over smoothly. Once the engine warms up, you’ll gradually move the choke to the “run” setting.
Using The Recoil Starter Correctly
Hold the mower steady with one hand on the handle and use your other hand to pull the starter rope briskly. Avoid slow or jerky pulls: a sharp, smooth pull sets the engine spinning at the right speed. If the mower doesn’t start on the first pull, wait a few seconds before trying again to avoid flooding. Once the engine catches, release the choke gradually as it warms up.
Troubleshooting Common Starting Issues
Addressing Engine Won’t Start Problems
If your mower refuses to start, first verify the basics: confirm fuel and oil levels are adequate, the spark plug is clean, and the air filter isn’t clogged. A simple spark check can help diagnose ignition issues. Also, ensuring the safety handle (blade control) is engaged is crucial as the mower won’t start otherwise.
Fixing Flooded Engine Situations
A flooded engine usually results from too much fuel entering the combustion chamber, often caused by over-priming or excessive pulls of the starter rope. To remedy this, remove the spark plug, dry it, and let the engine air out for about 10 minutes. Then, reinstall the plug and try starting the mower without pressing the primer bulb to let fresh air clear the excess fuel.
Maintaining Your Craftsman Lawn Mower For Reliable Starts
Regular Cleaning And Tune-Ups
Keeping your mower clean extends its life and ensures dependable starting. After each use, remove grass clippings and debris from the deck and engine area. Periodically change the oil, replace air filters, and swap spark plugs as recommended in your owner’s manual. Regular tune-ups not only improve starting but also maintain cutting performance.
Proper Storage Tips To Keep Your Mower Ready
If you plan to store your mower for an extended period, such as over winter, take steps to preserve it. Drain or stabilize the fuel to prevent gum deposits in the carburetor. Store the mower in a dry, sheltered place off the ground if possible. Disconnect the spark plug wire to prevent accidental starts and cover the mower with a breathable tarp to protect it from dust and moisture.
Conclusion
Mastering how to start your Craftsman lawn mower isn’t just about getting it running, it’s about understanding your machine’s needs for fuel, air, and safety. By regularly preparing, starting, troubleshooting, and maintaining your mower with the tips outlined here, you’ll enjoy a dependable mower that’s ready when you are. Keep these steps in mind, and your Craftsman will reward you with years of efficient, effortless lawn care.
