Frequently Asked Questions

Q: Which chainsaw and trimmer models is this spark plug compatible with?

A: This spark plug is compatible with BM6A, BPMR7A, RCJ6Y, RCJ7Y, and WSR5F spark plug types. It fits most 33cc–49cc gasoline-powered chainsaws, brush cutters, lawn mowers, and leaf blowers commonly used in agriculture and forestry applications.

Q: How do I replace a spark plug on my chainsaw or brush cutter?

A: First, ensure the engine is cool and disconnected. Use a spark plug wrench to unscrew the old plug by turning counter-clockwise. Insert the new alloy steel spark plug and hand-tighten before snugging it with the wrench — avoid overtightening. Reconnect the ignition wire and your engine is ready to start.

Q: What are the benefits of a copper core electrode spark plug for small engines?

A: Copper core electrodes offer superior electrical conductivity compared to standard plugs, resulting in a stronger spark, easier engine starting, better fuel combustion efficiency, and improved overall engine performance — ideal for high-demand garden power tools.
