The winter months can be a beautiful time, but they also bring the challenge of snow removal. Your Husqvarna snowblower is a powerful tool that can make this task much easier, but like any machine, it requires regular maintenance to ensure optimal performance. One crucial aspect of this maintenance is changing the spark plug. A worn-out spark plug can lead to a variety of issues, including difficulty starting, reduced engine power, and even engine damage.
Understanding how to change a spark plug on your Husqvarna snowblower is an essential skill for any owner. It’s a relatively straightforward procedure that can save you time and money in the long run. By performing this simple maintenance task, you can ensure your snowblower starts reliably, runs smoothly, and keeps you safe and efficient during the winter months.
Importance of Spark Plug Maintenance
The spark plug is the heart of your snowblower’s ignition system. It’s responsible for creating the spark that ignites the fuel-air mixture in the engine’s combustion chamber. Over time, the spark plug can wear down due to repeated use, exposure to extreme temperatures, and the buildup of carbon deposits.
A worn spark plug can lead to a variety of problems, including:
- Difficulty starting the engine
- Reduced engine power and performance
- Increased fuel consumption
- Engine misfires and rough idling
- Engine damage in severe cases
Regular spark plug changes are crucial for maintaining your snowblower’s reliability and longevity.

Before you begin, gather the following tools and materials:
| Tool | Description |
| Spark plug socket | A socket specifically designed to fit the spark plug. |
| Ratchet | Used to turn the spark plug socket. |
| Gap gauge | A tool for checking and adjusting the spark plug gap. |
| Torque wrench | Used to tighten the spark plug to the correct specifications. |
| New spark plug | Ensure it’s the correct type for your Husqvarna snowblower model. |

Step-by-Step Guide to Changing the Spark Plug
Locating the Spark Plug
The spark plug is typically located on the top or side of the engine. Consult your snowblower’s owner’s manual for the exact location. It will often be surrounded by a protective boot or cover.
Removing the Spark Plug Wire
Carefully pull the spark plug wire off the spark plug. The wire may be held in place by a clip or boot. Be gentle to avoid damaging the wire.
Removing the Old Spark Plug
Attach the spark plug socket to the ratchet and carefully insert it onto the spark plug. Turn the ratchet counterclockwise to loosen the spark plug. Do not overtighten when removing the plug.
Inspecting the Old Spark Plug
Once the spark plug is removed, inspect it for signs of wear and tear. Look for:
- Excessive carbon buildup
- Cracks or damage to the insulator
- Worn electrode
These signs indicate that the spark plug needs to be replaced.
Checking the Spark Plug Gap
Use a gap gauge to measure the distance between the center electrode and the ground electrode. The correct gap for your Husqvarna snowblower model is specified in the owner’s manual. Adjust the gap if necessary by carefully bending the ground electrode.
Installing the New Spark Plug
Carefully thread the new spark plug into the cylinder head by hand. Do not force it. Once it is hand-tight, use the spark plug socket and ratchet to tighten it to the manufacturer’s specifications. Use a torque wrench for accurate tightening. (See Also: How to Change Spark Plugs Subaru Outback? A Step-by-Step Guide)
