If the spark appears weak or sporadic, it may indicate a problem with the spark plug. In such cases, replacing the spark plug is recommended to restore optimal performance to the blower.
Assessing the spark color
In addition to the consistency of the spark, the color of the spark can also provide valuable insights into the condition of the spark plug. A healthy spark plug will produce a bright blue spark. If the spark appears yellow, orange, or even white, it may indicate a problem with the spark plug. Different colors may suggest fuel mixture issues or other underlying problems, which should be addressed to maintain the blower’s performance.
Resistance Testing
Gathering necessary tools
Resistance testing is another method to determine the condition of a spark plug. To perform this test, you will need a digital multimeter with an ohm function. It is important to gather the necessary tools before proceeding with the resistance test.
Determining the correct resistance value
The resistance value of a spark plug can vary depending on the manufacturer and model. Refer to the spark plug manufacturer’s specifications or the blower’s manual to determine the correct resistance value for your spark plug. This information will help you determine if the spark plug is within the acceptable range or if it needs to be replaced.
Testing the spark plug’s resistance
To test the spark plug’s resistance, disconnect the spark plug wire and remove the spark plug from the blower’s engine. Set the multimeter to the ohm function and measure the resistance by touching the multimeter’s probes to the terminal and electrode of the spark plug. Compare the measured resistance to the specified value. If the resistance is significantly higher or lower than the recommended range, it may indicate a faulty spark plug that requires replacement.

Compare with New Spark Plug
Understanding the appearance of a new spark plug
Before replacing the spark plug, it is helpful to understand the appearance of a new, properly functioning spark plug. A new spark plug will have a clean, undamaged electrode and an insulator with no signs of carbon deposits. Familiarizing yourself with the appearance of a new spark plug will allow you to compare it to the old spark plug and assess its condition accurately.
Comparing the differences between old and new spark plugs
Once you have removed the old spark plug, compare it side by side with a new spark plug. Look for any noticeable differences in the electrode, insulator, or overall condition. If the old spark plug shows signs of wear, damage, or excessive carbon deposits, it is a clear indication that it needs to be replaced. Comparing the differences between old and new spark plugs can give you valuable information about the condition of the old spark plug.
Replacement Considerations
Knowing the recommended interval for spark plug replacement
It is important to be aware of the recommended interval for spark plug replacement in your blower. Spark plugs typically need to be replaced after a certain number of operating hours or after a specified period.
