WINZOR Ignition Spark Plug for Trimmers and Chainsaws L7T

This L7T ignition spark plug is intended for compatible two-stroke chainsaws, brushcutters, trimmers and other small gasoline engines whose manufacturer specifies the use of an L7T short-thread plug. The plug produces a spark that ignites the compressed fuel and air mixture in the cylinder.

Several externally similar spark plugs are used for small engines. Therefore compatibility should be checked against the old plug's code, thread dimensions and the manufacturer's requirements. Engine displacement or equipment type alone is not sufficient.

A worn or fouled plug can make it harder to start the engine, cause ignition interruptions or worsen acceleration. However, the same symptoms may be caused by a faulty ignition coil, a damaged high-tension lead, an improperly adjusted carburetor, old fuel or low compression.

Before installation, compare the thread diameter, length, wrench size and type of sealing. Also check the heat range specified by the engine manufacturer.

Set the electrode gap according to the specific device's instructions. Then screw the plug in by hand first. This will reduce the risk of damaging the aluminum cylinder thread.

Do not overtighten the plug, as you may damage the thread or the sealing ring. Finally check that the plug tip is held firmly and that the engine idles stably and increases revs smoothly.
