**Always follow the instructions in your repair manual when doing repair or maintenance work on Outdoor Power Equipment. Manuals can be found at the manufacturers website.**
In this video I show how to gap a spark plug using a variety of spark plug gapping tools. Most spark plug gapping tools can be categorized as either wire gauge or leaf gauge gapping tools. Either tool can be used to gap a new spark plug, but a wire gauge gapping tool is better for gapping a used spark plug. In this video I show how to use these tools and why one is better than the other.
Thank you for watching!
