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.
The Sear's website recommends spark plug number DJ7Y, but the brand is not listed.
