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.
plug gap should be .025" http://store.chainsawr.com/
Depending on the model there should be a cover above the throttle handle. The spark plug should be under that cover.
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.
The spark plug for a Stihl FS36 is a Bosch WSR6F gapped at .025
Spark plug gap is .020 [or 0.5mm metric] Bosch plug numbers are 7547 and WSR6F [either can be used] Can be converted to Champion or NGK, etc. with an online conversion chart. T'care, Mike
