Product Description

This is a spark plug, and it is used in a variety of outdoor equipment. The spark plug ignites the fuel in the engine by producing a small spark. This part is RDJ7Y, meaning it is a resistor type, with a shell design thread size of 14mm, reach of 13/40-inch (tapered seat), and 5/8-inch hex. The heat range is 7 for automotive, small engine, and ordnance, with a standard projected core nose. If this part has fouled (the tip is burnt or damaged) you will need to replace it. If the engine is not starting or is running poorly, you may need a new spark plug. We recommend draining the fuel from the tank, and removing the spark plug before making repairs on your machine.
