Winter’s icy grip can be a real challenge, but having a reliable snowblower at your disposal can make all the difference. These powerful machines clear driveways and walkways, allowing you to navigate snowy landscapes with ease. However, like any complex machinery, snowblowers require proper maintenance to ensure peak performance. One crucial aspect of snowblower upkeep is changing the spark plug. The spark plug ignites the fuel-air mixture in the engine, and a worn-out or fouled spark plug can lead to a range of problems, from reduced power and starting difficulties to complete engine failure.
Understanding how to change a spark plug on your Briggs and Stratton snowblower is an essential skill for every snowblower owner. It’s a relatively straightforward task that can save you time, money, and potential headaches down the road. By following the steps outlined in this comprehensive guide, you’ll be able to tackle this maintenance chore with confidence and keep your snowblower running smoothly throughout the winter season.
Gathering Your Tools and Supplies
Before you begin, it’s important to gather all the necessary tools and supplies. Having everything on hand will make the process smoother and more efficient. Here’s a list of what you’ll need:
- New spark plug (check your owner’s manual for the correct type and gap)
- Spark plug socket (the correct size for your snowblower’s spark plug)
- Ratchet wrench
- Gap gauge (to adjust the spark plug gap if necessary)
- Torque wrench (optional, but recommended for proper tightening)
- Safety glasses
- Work gloves
- Clean cloth or rag
Preparing Your Snowblower
Safety should always be your top priority when working with any machinery. Before you start, make sure to disconnect the spark plug wire to prevent accidental engine starts. Locate the spark plug wire, which is typically a thick, insulated cable connected to the spark plug. Carefully pull the boot off the spark plug.
Next, ensure the snowblower is on a level surface and the engine is cool to the touch. If the engine is warm or hot, allow it to cool down completely before proceeding. This will prevent burns and potential damage to the spark plug.
Removing the Old Spark Plug
With the spark plug wire disconnected, you can now remove the old spark plug. Locate the spark plug, which is usually on the side or top of the engine. Use the spark plug socket and ratchet wrench to carefully loosen the spark plug. Turn the wrench counterclockwise to loosen the plug.
Be careful not to overtighten the wrench, as this can damage the spark plug threads. Once the spark plug is loose, you can remove it by hand. Inspect the old spark plug for signs of wear or damage. A worn spark plug may have a blackened or oily electrode, a cracked insulator, or a gap that is too wide or too narrow. (See Also: How to Splice Spark Plug Wire? The Ultimate Guide)
Inspecting the Spark Plug Gap
The spark plug gap is the distance between the central electrode and the ground electrode. This gap is crucial for proper ignition. Use a gap gauge to measure the gap of the new spark plug. Compare the measurement to the gap specified in your snowblower’s owner’s manual. If the gap is incorrect, you can adjust it using a small flat-head screwdriver.
To adjust the gap, gently bend the ground electrode until the gap gauge fits snugly between the electrodes. Be careful not to bend the electrode too much, as this can damage the spark plug. Once the gap is correct, clean the spark plug threads with a clean cloth or rag to remove any dirt or debris.
Installing the New Spark Plug
With the new spark plug gapped correctly, you can now install it into the engine. Carefully thread the spark plug into the spark plug hole by hand. Make sure the spark plug is seated properly and straight. Once the spark plug is hand-tightened, use the spark plug socket and ratchet wrench to tighten it further.
Avoid overtightening the spark plug, as this can damage the threads. If you have a torque wrench, use it to tighten the spark plug to the torque specification listed in your owner’s manual. This will ensure that the spark plug is securely tightened without being overtightened.
Reattaching the Spark Plug Wire
With the new spark plug securely installed, you can now reattach the spark plug wire. Carefully align the boot of the spark plug wire with the spark plug and push it firmly onto the spark plug. Make sure the boot is securely seated and there are no gaps or loose connections.
Double-check that all connections are secure and that the spark plug wire is properly routed. Once you’ve reattached the spark plug wire, you can start your snowblower to test the new spark plug. (See Also: How to Change Spark Plugs on 2004 Hyundai Sonata V6? – Easy DIY Guide)
Checking for Proper Operation
After installing the new spark plug, start your snowblower and let it run for a few minutes. Listen for any unusual noises or vibrations. Check the engine performance for any signs of hesitation or misfiring. If the engine runs smoothly and without problems, you’ve successfully changed the spark plug on your Briggs and Stratton snowblower.
