A SPARK PLUG TESTING KIT

摘要

There is disclosed a spark plug testing kit allowing for safe and convenient testing of petrol engines comprising a spark observation device; a spark plug opening engaging device; and an earth lead electrically connecting the spark observation device and the spark plug opening engaging device. The spark observation device comprises a transparent observation chamber so as to allow for the viewing of the spark gap of a spark plug installed therein in use. The observation chamber is substantially airtight so as to substantially prevent or reduce the possibility of the inadvertent ignition of fuel. The spark plug opening engaging device is configured for engaging a spark plug opening of the spark plug once the spark plug has been removed for observation so as to substantially prevent debris from falling in through the opening and serve as an engine block electrical connection contact for the earth lead. Furthermore, the spark plug opening engaging device comprises at least one exhaust for chamber decompression.
