As the winter season approaches, homeowners and property managers alike are gearing up to tackle the snow-covered landscapes that come with it. One essential tool for clearing snow is the snowblower, a machine that relies on a spark plug to ignite the fuel and generate power. Over time, the spark plug can become worn out, leading to decreased performance, poor starting, and even engine damage. In this comprehensive guide, we’ll walk you through the process of changing the spark plug on a Toro snowblower, ensuring your machine runs smoothly and efficiently throughout the winter season.
Preparation is Key
Before you start the process, make sure you have the necessary tools and materials. You’ll need a spark plug socket, a ratchet, and a new spark plug that matches the specifications of your Toro snowblower. It’s also a good idea to consult your owner’s manual for specific instructions and recommendations.
Spark Plug Specifications
The spark plug specifications for your Toro snowblower can be found in the owner’s manual or on the manufacturer’s website. Make sure to note down the following information:
- Spark plug type (e.g., NGK, Champion, etc.)
- Spark plug gap (measured in thousandths of an inch)
- Spark plug thread size (measured in inches)
Locating the Spark Plug
The spark plug on a Toro snowblower is typically located on the side of the engine or near the carburetor. Consult your owner’s manual or refer to the diagram below to locate the spark plug on your specific model:
| Model | Spark Plug Location |
|---|---|
| Toro Power Clear 721 QZE | Side of the engine, near the carburetor |

Removing the Spark Plug
Once you’ve located the spark plug, use a spark plug socket to remove it. Insert the socket into the spark plug well and turn it counterclockwise until the plug is loose. Remove the spark plug and set it aside.
Spark Plug Removal Tips
When removing the spark plug, be careful not to touch the spark plug wire or the spark plug boot to prevent damage or electrical shock. If the spark plug is stuck, use a spark plug removal tool or a penetrating oil to loosen it. (See Also: Will Bad Spark Plugs Cause Overheating? The Hidden Dangers)
