My 16" Craftsman 36 cc chainsaw manual calls out for a Champion RCJ7Y....if that is the same size chainsaw as yours, I would go with that plug.
Spark plug gap should be .025 http://store.chainsawr.com/
Spark Plug gap is .025
Depending on the model there should be a cover above the throttle handle. The spark plug should be under that cover.
.030
0.020 in or 0.50mm
Plug gap should be .025" http://store.chainsawr.com/
Champion RDJ7Y is the correct number.
Mine has original plug, it is a: Champion # CJ8Y
This is one of the dumbest questions i have ever heard of. If you are not sure if your GAS chainsaw has a spark plug i would highly suggest not using it because you are an idiot
.030
.030"
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.
