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.

To determine the correct spark plug for a Sears chainsaw, you should first check the owner's manual or the chainsaw's specifications for the recommended spark plug model. Commonly used spark plugs for Sears chainsaws include models like Champion RCJ7Y or NGK BPMR7A, but this can vary by specific model. If the manual is unavailable, you can also consult a local hardware store or a chainsaw specialist for assistance in finding the right spark plug. Always ensure the spark plug matches the required size and specifications for optimal performance.
Depending on the model there should be a cover above the throttle handle. The spark plug should be under that cover.

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
