The warm weather has finally arrived, and your lawn is begging for a trim. You pull out your trusty Craftsman lawnmower, ready to tackle the task. But then, it happens – the familiar sound of the engine sputtering to life is replaced by a frustrating silence. You’ve got a cranky Craftsman mower that refuses to cooperate. Don’t worry, you’re not alone! Many homeowners encounter this issue, and with a little guidance, you can get your lawnmower running smoothly again. This article will walk you through the essential steps of cranking a Craftsman lawn mower, helping you avoid common pitfalls and troubleshoot any issues along the way.
A Quick Overview
The process of cranking a Craftsman lawn mower typically involves several steps, starting with ensuring the mower is properly prepped and fueled. Next, you’ll engage the choke and pull the starter cord, aiming for a smooth and steady pull. After the engine starts, you’ll need to gradually disengage the choke and let the mower warm up. If the engine doesn’t start, you’ll need to troubleshoot potential issues, from a clogged carburetor to a dead battery.
Step 1: Prep Your Lawn Mower
Before you even attempt to crank your Craftsman lawn mower, it’s essential to have it prepped and ready to go. Here’s how:
1.1. Check the Fuel Level and Type
Start by checking the fuel level in the tank. If it’s low, fill it up with fresh, high-octane gasoline. Make sure you’re using the correct type of fuel specified in your mower’s manual, as using the wrong fuel can lead to engine damage.
1.2. Inspect the Spark Plug
The spark plug is crucial for igniting the fuel and air mixture. Remove the spark plug wire and then use a spark plug wrench to remove the spark plug. Inspect the spark plug for signs of wear or damage, such as a cracked insulator or electrode. If the spark plug looks worn, replace it with a new one.
1.3. Check the Air Filter
The air filter helps prevent dust and debris from entering the engine. A dirty air filter can restrict airflow, leading to engine problems. Remove the air filter cover and check the filter. If it’s dirty, replace it with a new one.
Step 2: Prime the Engine (If Applicable)
Many Craftsman lawnmowers feature a priming bulb. This bulb helps introduce fuel into the carburetor, making it easier to start the engine. If your mower has a priming bulb, depress it several times before attempting to start the engine.
Step 3: Engage the Choke
The choke helps enrich the fuel-air mixture when the engine is cold. This makes it easier to start. Locate the choke lever, usually on the side of the mower. Move the choke lever to the “choke” or “on” position.
Step 4: Pull the Starter Cord
With the choke engaged, it’s time to start cranking the engine. Hold the starter cord handle firmly and give a quick, decisive pull. Aim for a smooth and steady pull, avoiding jerking motions.
4.1. Troubleshooting Issues While Pulling the Cord
If the engine doesn’t start immediately, don’t despair. Here are some common issues and troubleshooting steps:
- No Fuel Flow: If you’re sure you have fuel in the tank, check the fuel lines for any kinks or clogs.
- Clogged Air Filter: A clogged air filter can restrict airflow and prevent the engine from starting. If you haven’t already, inspect and clean or replace the air filter.
- Spark Plug Problems: If the spark plug is fouled or damaged, it won’t ignite the fuel mixture.
- Flooded Engine: If you’ve pulled the starter cord too many times or left the choke on too long, the engine may be flooded. To resolve this, open the choke lever and pull the starter cord a few times to clear out the excess fuel.
Step 5: Disengage the Choke Gradually
Once the engine starts, you’ll need to gradually disengage the choke. Start by moving the choke lever to the “half choke” position. After the engine runs smoothly for a few seconds, you can slowly move the lever to the “off” position.
Step 6: Let the Engine Warm Up
Allow the engine to warm up for a few minutes before you start mowing. This will help the engine run smoothly and efficiently.
Step 7: Maintaining Your Craftsman Lawn Mower
To keep your Craftsman lawn mower running smoothly and avoid cranking problems, regular maintenance is key. Here are some maintenance tips:
7.1. Regular Oil Changes
Check your owner’s manual for the recommended oil change interval for your model. Using the appropriate type of oil is crucial for engine health.
7.2. Clean the Mower Regularly
After each use, clean the mower deck, underside, and blade. This will help prevent buildup of grass clippings and debris, which can lead to engine problems.
7.3. Sharpen the Blade
A sharp blade cuts cleanly, preventing uneven cuts and damage to your lawn. Sharpen your blade regularly, following the instructions in your owner’s manual.
Step 8: Seek Professional Help When Needed
If you’re still struggling to crank your Craftsman lawn mower, don’t be afraid to seek professional help. A local repair shop can diagnose and address any underlying issues, ensuring your mower runs smoothly for years to come.
Conclusion
Cranking a Craftsman lawn mower can seem daunting, but it’s a simple process when you follow the right steps. By preparing your mower, engaging the choke properly, and understanding common troubleshooting steps, you can easily get your mower running smoothly. Remember to follow the maintenance tips to keep your lawn mower in optimal condition, ensuring years of reliable performance. Now go forth and conquer those overgrown lawns!
FAQ
Why is my Craftsman lawnmower hard to crank?
There are several reasons why your Craftsman lawnmower might be difficult to crank. The most common reasons include:
* Old or bad gas: Old gasoline can gum up the carburetor and make it difficult for the engine to start.
* Dirty air filter: A dirty air filter restricts airflow to the engine, making it harder to start.
* Spark plug problems: A fouled spark plug or a spark plug with a gap that’s too wide can prevent the engine from starting.
* Low oil level: If the oil level is too low, the engine won’t start.
What type of gas should I use in my Craftsman lawnmower?
You should always use fresh, unleaded gasoline with an octane rating of 87 or higher in your Craftsman lawnmower. Do not use gasoline that is more than 30 days old, as it can degrade and cause starting problems. Additionally, avoid using fuel additives, as they can damage your lawnmower’s engine.
How often should I change the oil in my Craftsman lawnmower?
It’s recommended to change the oil in your Craftsman lawnmower every 25 hours of operation or at the beginning of each mowing season.

How do I check the spark plug in my Craftsman lawnmower?
To check the spark plug, you’ll need to remove it from the engine. Use a spark plug socket wrench to loosen and remove the spark plug. Once removed, inspect the spark plug for any signs of wear, damage, or fouling. If the spark plug is fouled or damaged, replace it with a new one. Also, ensure the gap between the spark plug electrodes is correct, as specified in your owner’s manual.
What should I do if my Craftsman lawnmower won’t start?
If your Craftsman lawnmower won’t start, there are several troubleshooting steps you can take. First, check the fuel level and ensure you’re using fresh gasoline. Next, inspect the air filter and clean or replace it if it’s dirty. Then, check the spark plug and make sure it’s clean and has the correct gap. Finally, check the oil level and top it off if needed. If none of these steps work, you may need to seek help from a qualified mechanic.
Can I use a battery-powered starter to crank my Craftsman lawnmower?
No, you cannot use a battery-powered starter to crank your Craftsman lawnmower. These mowers are designed to be started manually using the pull cord. Attempting to use an external starter could damage the engine or other components of your lawnmower.
