The correct spark plug for a Stihl 024 is an RCJ6Y (Champion), BPMR7A (NGK), or a WSR6F (Bosch). Make sure that the gap is set to 0.020 inches.
Depending on the model there should be a cover above the throttle handle. The spark plug should be under that cover.
To change the spark plug on a Stihl Wood Boss 024 AV chainsaw, first ensure the chainsaw is turned off and cool. Remove the spark plug cover using a screwdriver, then use a spark plug wrench to unscrew and remove the old spark plug. Check the gap on the new spark plug, install it by hand to avoid cross-threading, and tighten it with the wrench. Finally, replace the spark plug cover securely before starting the chainsaw.

If it has contact breakers and a condensor, check that the contact foot that rides the timing cam, is not worn down. Check the contact gap and the contact faces for pits and spikes. The faces should be flat, clean and smooth. The gap should be as per the owners handbook/ motor spec plate. Check for spark at HT lead plug cap before checking plug for spark.
correct plug is NGK BPMR7A
