When Should You Replace The Spark Plug On Your MTD Chainsaw?
As part of routine chainsaw maintenance, we recommend inspecting your spark plug for damage. A decent rule of thumb is to replace chainsaw spark plugs after 100 hours of use. It is best to replace the spark plug sooner if it is damaged, therefore check the spark plug on your chainsaw as part of periodic maintenance and replace it if there is damage or buildup.
