The SynchroKing 8 is a universal vacuum synchronization/balancing tool for both carburetors and throttle valve bodies. It suitable for any combustion engine with four intake ports from cars, motorcycles, mopeds, scooters, carts, mowers and outboard engines.  The SynchroKing 8 is designed to provide a compact, easy to use and economical synchronization tool for home workshop use. The SynchroKing 8 is primarily designed for use with engines with four inlet manifolds but is in principle suitable for any engine with more than one intake. If not all eight ports are used, the device will automatically ignore the sensor input from the disconnected ports, making it possible to use the device on 2 through 8 manifold engines. The device comes with a set of 8 of each M5 and M6 port adapters, enabling easy connection to the vacuum test ports on most vehicles.
