To perform a weed eater spark plug replacement, first ensure the engine is cool. Locate the spark plug on the engine and use a spark plug wrench to remove it. Check the gap on the new spark plug and adjust if necessary. Install the new spark plug by hand, then tighten it with the wrench. Finally, reconnect the spark plug wire and test the weed eater to ensure it is running smoothly.
