This article will walk you through the simple steps to get your Craftsman lawn mower running smoothly, covering everything from basic troubleshooting to more advanced tips.
Before we dive in, let’s quickly clarify that Craftsman mowers come in a variety of models, each with its own quirks and nuances. This guide covers the most common types, but if you’re still stuck, refer to your owner’s manual or contact Craftsman customer service for specific instructions.
The Basics: Starting a Craftsman Lawn Mower
Starting your Craftsman lawn mower is a straightforward process, but it’s essential to understand the key components and their functions:
- The Ignition Key: Most Craftsman mowers use a traditional key to start the engine.
- The Choke: This lever helps enrich the fuel mixture for easier starting, especially when the engine is cold.
- The Throttle: This lever controls the engine’s speed.
- The Primer Bulb: Some Craftsman models feature a primer bulb, which helps prime the engine with fuel.
Starting a Cold Engine:
- Fuel: Ensure the fuel tank has fresh, clean gasoline.
- Choke: Engage the choke lever.
- Prime: If your mower has a primer bulb, press it a few times to fill the carburetor with fuel.
- Ignition: Insert the key and turn it to the start position.
- Start: Pull the recoil starter cord firmly and consistently until the engine starts.
- Throttle: Once the engine is running, gradually disengage the choke and adjust the throttle to your desired speed.
Starting a Warm Engine:
- Fuel: Check the fuel level.
- Choke: Leave the choke disengaged.
- Prime: If applicable, prime the carburetor.
- Ignition: Insert the key and turn it to the start position.
- Start: Pull the recoil starter cord until the engine starts.
- Throttle: Adjust the throttle to your desired speed.
Troubleshooting Common Starting Problems
If your Craftsman mower refuses to cooperate, don’t despair. Here are some common starting issues and their solutions:
1. Lack of Fuel:
- Check the fuel tank: Ensure it’s not empty.
- Verify fuel freshness: Old gas can gum up the engine. Use fresh gas or add a fuel stabilizer.
- Examine the fuel lines: Look for any cracks or leaks. Replace damaged lines.
2. Spark Plug Issues:
- Check the spark plug: Remove the spark plug and inspect it for wear or damage. Replace it if necessary.
- Test the spark plug: Connect the spark plug wire to the spark plug and hold it near a grounded metal surface while pulling the starter cord. A spark should jump across the gap.
- Clean the spark plug: If the spark plug is dirty, clean it with a wire brush and gap it correctly according to your owner’s manual.
3. Clogged Air Filter:
- Inspect the air filter: A dirty air filter restricts airflow to the engine. Remove and clean or replace the filter.
- Check for debris: Make sure there’s no debris blocking the air intake.
4. Carburetor Problems:
- Check the carburetor: A clogged or malfunctioning carburetor can prevent fuel from reaching the engine.
- Clean the carburetor: Use a carburetor cleaner and follow the instructions on the product label.
- Replace the carburetor: If cleaning doesn’t solve the problem, the carburetor may need replacement.
5. Battery Issues (For Electric Mowers):
- Check the battery: If your mower is electric, make sure the battery is charged.
- Replace the battery: If the battery is old or faulty, replace it.
- Ensure the battery terminals are clean: Corrosion can hinder battery function. Clean the terminals with a wire brush.
