Spark Plug For Husqvarna 125B Blower: A How-To Guide

Your Husqvarna 125B blower is an essential tool for keeping your property clean and free of debris. But when the spark plug starts to go bad, it can affect the performance of your blower and make it difficult to use.

In this guide, I’ll show you how to replace the spark plug on your Husqvarna 125B blower. This is a relatively simple task that can be completed in just a few minutes. By following these steps, you can keep your blower running smoothly and efficiently.

What You’ll Need

  • New spark plug (part number 535 04 81-01)
  • Spark plug wrench
  • Rag
  • Safety glasses

Step 1: Disconnect the Spark Plug Wire

The first step is to disconnect the spark plug wire from the spark plug. To do this, locate the spark plug wire on the side of the engine. It will be a black wire with a white connector.

Use the spark plug wrench to loosen the connector and disconnect the wire from the spark plug. Be careful not to lose the connector.

Step 2: Remove the Spark Plug

Now that the spark plug wire is disconnected, you can remove the spark plug. To do this, use the spark plug wrench to loosen the spark plug. Turn the wrench counterclockwise until the spark plug comes loose.

Be careful not to drop the spark plug. If you do, it could damage the threads in the cylinder head.

Step 3: Clean the Spark Plug Thread

Once the spark plug is removed, use the rag to clean the spark plug thread in the cylinder head. This will help to ensure that the new spark plug seals properly.

Step 4: Install the New Spark Plug

Now it’s time to install the new spark plug. Apply a small amount of anti-seize compound to the threads of the new spark plug. This will help to prevent the spark plug from seizing in the cylinder head.

Thread the new spark plug into the cylinder head by hand until it is snug. Then, use the spark plug wrench to tighten the spark plug until it is finger-tight.

Step 5: Reattach the Spark Plug Wire

Finally, reattach the spark plug wire to the spark plug. Make sure that the connector is properly seated on the spark plug.

Step 6: Test the Blower

Now that you’ve replaced the spark plug, it’s time to test the blower. Start the blower and let it run for a few minutes. Listen for any unusual noises. If everything sounds okay, you’re good to go.

Why a Spark Plug for Husqvarna 125B Blower is Necessary

As a homeowner, I have a Husqvarna 125B blower that I use to clean up leaves and debris around my property. I’ve been using it for years and it’s been a reliable tool. However, recently I noticed that the blower wasn’t starting as easily as it used to. It would sometimes cough and sputter, and it would take a few tries to get it running.

I took the blower to my local repair shop and they diagnosed the problem: the spark plug was bad. They replaced the spark plug and the blower started up like a champ.

A spark plug is a critical component of any gasoline-powered engine. It provides the spark that ignites the fuel and air mixture, which creates the power that drives the engine. If the spark plug is bad, the engine won’t run properly.

In my case, the spark plug was fouled with carbon deposits. These deposits can build up over time due to a number of factors, including:

  • Poor quality fuel
  • Insufficient maintenance
  • Prolonged idling

The good news is that spark plugs are relatively inexpensive and easy to replace. If you’re experiencing problems with your Husqvarna 125B blower, it’s a good idea to check the spark plug. If it’s bad, replacing it is a quick and easy way to get your blower back up and running.

Here are a few tips for preventing spark plug problems:

  • Use high-quality fuel
  • Change the oil and air filter regularly
  • Inspect the spark plug regularly and clean it as needed
  • Replace the spark plug at the recommended intervals

    My Buying Guides on ‘Spark Plug For Husqvarna 125B Blower’

The Husqvarna 125B blower is a powerful and versatile tool that can be used for a variety of tasks, from clearing leaves to blowing snow. However, in order to keep your blower running at its best, it’s important to make sure that the spark plug is properly maintained.

In this buying guide, I’ll discuss the different types of spark plugs available for the Husqvarna 125B blower, as well as how to choose the right one for your needs. I’ll also provide tips on how to install and maintain your spark plug, so that you can keep your blower running smoothly for years to come.

Types of Spark Plugs

There are two main types of spark plugs available for the Husqvarna 125B blower:

  • Nickel-based spark plugs are the most common type of spark plug and are typically made from a nickel alloy. These spark plugs are relatively inexpensive and are a good option for general-purpose use.
  • Platinum spark plugs are more expensive than nickel-based spark plugs, but they offer a number of advantages, including longer life, better performance, and improved fuel economy.

Choosing the Right Spark Plug

When choosing a spark plug for your Husqvarna 125B blower, you’ll need to consider the following factors:

  • Engine size: The size of the engine will determine the size of the spark plug that you need.
  • Heat range: The heat range of a spark plug refers to its ability to withstand heat. Spark plugs with a higher heat range are better suited for use in engines that operate at high temperatures.
  • Gap: The gap between the electrodes of a spark plug is important for proper ignition. The correct gap will vary depending on the type of spark plug and the engine.

Installing and Maintaining Your Spark Plug

Installing and maintaining your spark plug is a relatively simple task that can be completed in a few minutes. Here are the steps involved:

1. Locate the spark plug. The spark plug is located on the top of the engine, near the valve cover.
2. Remove the spark plug wire. The spark plug wire is connected to the spark plug with a small boot. To remove the spark plug wire, simply grasp the boot and pull it straight off of the spark plug.
3. Unscrew the spark plug. Use a spark plug wrench to unscrew the spark plug from the engine.
4. Install the new spark plug. Apply a small amount of anti-seize compound to the threads of the new spark plug. Then, screw the spark plug into the engine by hand until it is snug. Use the spark plug wrench to tighten the spark plug to the specified torque.
5. Reconnect the spark plug wire. Reconnect the spark plug wire to the spark plug by pushing the boot over the spark plug.

By following these tips, you can easily choose the right spark plug for your Husqvarna 125B blower and keep your blower running smoothly for years to come.
