Types of Husqvarna Spark Plugs
Husqvarna spark plugs can be classified based on their design, materials, and performance characteristics. The most common types include:
- Standard Spark Plugs:These are basic spark plugs with a single electrode and a copper core. They are suitable for general-purpose applications and provide reliable ignition.
- Platinum Spark Plugs:Platinum spark plugs feature a platinum electrode, which offers increased durability and longer life compared to standard spark plugs. They are ideal for high-performance engines or those operating in demanding conditions.
- Iridium Spark Plugs:Iridium spark plugs have an iridium electrode, which is even more durable and resistant to wear than platinum. They provide excellent ignition and are suitable for high-compression engines or those requiring extended spark plug life.
- Double Platinum Spark Plugs:These spark plugs have two platinum electrodes, ensuring consistent ignition and extended lifespan. They are designed for heavy-duty applications or engines that experience frequent stop-and-go operation.
Spark Plug Gap and Torque Specifications
Maintaining proper spark plug gap and torque specifications is crucial for optimal engine performance and longevity. The gap between the spark plug’s electrodes determines the strength and timing of the spark, while the torque applied during installation ensures a secure fit and prevents damage to the plug or engine.
Recommended Gap and Torque Settings
The recommended spark plug gap and torque settings vary depending on the specific Husqvarna engine model. Refer to the table below for the correct specifications for your engine:
| Engine Model | Spark Plug Gap (in) | Torque (ft-lbs) |
|---|---|---|
| K970 | 0.028 | 12-15 |
| K950 | 0.030 | 12-15 |
| K930 | 0.032 | 12-15 |
Spark Plug Replacement Intervals
The longevity of spark plugs in Husqvarna engines depends on various factors, including the type of engine, operating conditions, and fuel quality. Understanding these factors can help determine the appropriate replacement intervals.
Generally, spark plugs in Husqvarna engines should be replaced every 100-200 operating hours or annually, whichever comes first. However, it’s essential to consider the following factors when determining the replacement interval:
Operating Conditions
- Heavy Load:Engines operating under heavy loads or in dusty environments may require more frequent spark plug replacements.
- Extreme Temperatures:Engines operating in extreme cold or hot conditions can experience accelerated spark plug wear.
- Fuel Quality:Low-quality fuel or fuel with high ethanol content can lead to carbon buildup on spark plugs, shortening their lifespan.

Troubleshooting Spark Plug Issues
Spark plugs play a crucial role in the ignition system of an engine. They provide the spark that ignites the air-fuel mixture, allowing the engine to run smoothly. However, spark plugs can sometimes malfunction, leading to various engine problems. Here’s a guide to help you troubleshoot spark plug issues:
Common Symptoms of Spark Plug Problems
- Engine misfires or hesitates
- Engine runs rough or stalls
- Poor fuel economy
- Difficulty starting the engine
- Check engine light illuminates
Troubleshooting Guide
-*Check for spark
Remove the spark plug wire from the spark plug and hold it close to a metal part of the engine. Have someone crank the engine. If there’s no spark, the spark plug may be faulty.
-*Inspect the spark plug
Remove the spark plug and inspect it for damage, such as cracks, broken electrodes, or excessive wear. If the spark plug is damaged, it should be replaced.
-*Clean the spark plug
If the spark plug is not damaged, it may be dirty or fouled. Clean the spark plug using a wire brush or spark plug cleaner.
-*Check the spark plug gap
The spark plug gap is the distance between the center electrode and the ground electrode. The gap should be set to the manufacturer’s specifications. Use a feeler gauge to measure the gap and adjust it if necessary.
-*Replace the spark plug
If the spark plug is damaged, dirty, or has an incorrect gap, it should be replaced. Use a spark plug wrench to remove the old spark plug and install the new one.
Spark Plug Maintenance Tips
Regular spark plug maintenance is crucial for ensuring optimal engine performance. Here are some tips to help you keep your spark plugs in top condition:
To maintain spark plugs in optimal condition, follow these steps:
Cleaning Spark Plugs
Cleaning spark plugs removes carbon deposits and other contaminants that can hinder their performance. To clean spark plugs:
- Use a wire brush or compressed air to remove loose debris.
- Dip the spark plugs in a commercial spark plug cleaner or a solution of carburetor cleaner and water (50:50).
- Let them soak for 15-30 minutes.
- Use a soft cloth or brush to gently scrub away any remaining deposits.
- Rinse the spark plugs thoroughly with clean water and allow them to dry completely.
Inspecting Spark Plugs, Husqvarna spark plug chart
Inspecting spark plugs can provide valuable insights into engine health and potential issues. To inspect spark plugs:
- Examine the electrode gap. It should be within the manufacturer’s specified range (typically 0.025-0.035 inches).
- Check for signs of wear or damage, such as cracks, chips, or excessive erosion.
- Observe the color of the spark plug tip. A light tan or gray color indicates optimal combustion, while black or white deposits can signal potential problems.
Adjusting Spark Plugs
Adjusting spark plugs ensures proper ignition timing and optimal engine performance. To adjust spark plugs:
- Use a spark plug gap gauge to measure the electrode gap.
- Carefully bend the side electrode to increase or decrease the gap as needed.
- Reinstall the spark plugs with the correct torque, as specified by the manufacturer.
