Winter is upon us, and with it comes the dreaded snow. While snow can be beautiful, it can also bring about the inconvenience of having to clear your driveway and walkways. Thankfully, snow blowers are here to help, but like any machine, they require regular maintenance to ensure they’re running smoothly. One essential maintenance task is changing the spark plug.

This guide will walk you through the process of changing the spark plug in your snow blower, enabling you to tackle the winter season with confidence.

Why Change Your Spark Plug?

Spark plugs are crucial components in your snow blower‘s engine. They ignite the air-fuel mixture, allowing the engine to run. Over time, spark plugs wear out and can cause problems like:

  • Difficulty starting: A worn-out spark plug may not generate enough spark to ignite the fuel, making it difficult to start your snow blower.
  • Rough running: A worn-out spark plug can lead to misfires, causing the engine to run roughly and lose power.
  • Increased fuel consumption: A worn-out spark plug can cause the engine to burn fuel inefficiently, leading to increased fuel consumption.

Changing your spark plug regularly can help prevent these issues and ensure your snow blower runs smoothly all winter long.

Gather Your Tools and Materials

Before you begin, gather the following tools and materials:

  • New spark plug: Make sure to purchase a spark plug that is the correct type and size for your snow blower. Consult your owner’s manual or a reputable parts supplier for the correct specification.
  • Socket wrench: You’ll need a socket wrench that fits the size of your spark plug.
  • Spark plug gap tool: This tool is used to adjust the gap between the spark plug electrodes.
  • Gloves: Wear gloves to protect your hands from dirt and grease.
  • Safety glasses: Protect your eyes from flying debris.
  • Clean rag: Use this to clean the spark plug area.

Locate the Spark Plug

The first step is to locate the spark plug on your snow blower. It’s typically located on the top of the engine, near the air filter. Refer to your owner’s manual for the exact location on your specific model.

Disconnect the Spark Plug Wire

Once you’ve located the spark plug, you need to disconnect the spark plug wire. This is a safety precaution to prevent accidental sparking and injury. Gently pull the wire off the spark plug terminal.

Remove the Old Spark Plug

Now, use your socket wrench to remove the old spark plug. Be careful not to drop the spark plug into the engine cylinder.

Inspect the Old Spark Plug

Before installing the new spark plug, take a moment to inspect the old one. Look for signs of wear and tear, such as:

  • Electrode wear: The electrode tip should be sharp and pointed. If it’s rounded or worn down, it’s time for a new spark plug.
  • Carbon buildup: Carbon buildup on the electrodes can hinder spark generation. If you see excessive buildup, it’s a sign that the spark plug needs to be replaced.
  • Cracks or damage: Inspect the spark plug for any cracks or damage. If you find any, replace the spark plug immediately.

Install the New Spark Plug

Now, it’s time to install the new spark plug. Before you do, make sure to check the spark plug gap using a spark plug gap tool. The gap should be set according to the specifications in your owner’s manual.

Once the gap is set, screw the new spark plug into the cylinder head using your socket wrench. Tighten it securely, but avoid overtightening, which can damage the threads.

Reconnect the Spark Plug Wire

After installing the new spark plug, reconnect the spark plug wire to the terminal. Ensure it’s securely connected.

Start the Engine

With the new spark plug installed, start the engine and let it run for a few minutes. Listen for any unusual noises or rough running. If everything sounds normal, you’ve successfully changed the spark plug.

Final Thoughts: Keeping Your Snow Blower Running Smoothly

Changing the spark plug in your snow blower is a simple maintenance task that can make a big difference in its performance. By following these steps, you can ensure your snow blower is ready to tackle any winter storm.

Questions You May Have

Q: How often should I change the spark plug in my snow blower?

A: It’s generally recommended to change the spark plug every 100 hours of operation or annually, whichever comes first. However, consult your owner’s manual for specific recommendations for your snow blower model.

Q: What if I don’t have a spark plug gap tool?

A: If you don’t have a spark plug gap tool, you can use a thin piece of cardboard or a feeler gauge to adjust the gap. However, a spark plug gap tool is the most accurate and reliable way to set the gap.

Q: Can I use any type of spark plug in my snow blower?

A: No, it’s important to use the correct type and size of spark plug for your snow blower. Using the wrong spark plug can damage your engine. Consult your owner’s manual or a reputable parts supplier for the correct specification.

Q: What are some other maintenance tasks I should do for my snow blower?

A: In addition to changing the spark plug, you should also perform other regular maintenance tasks, such as:

  • Changing the oil: This should be done every 25 hours of operation or annually, whichever comes first.
  • Cleaning the air filter: A dirty air filter can restrict airflow to the engine, reducing performance.
  • Checking the fuel lines: Make sure the fuel lines are free of cracks and leaks.
  • Inspecting the belts: Check the drive belts for wear and tear.
  • Greasing the moving parts: Lubricate the moving parts to prevent rust and wear.

By performing these maintenance tasks regularly, you can keep your snow blower running smoothly and reliably all winter long.
