Application
The SynchroKing 4S Mk2
is a universal vacuum synchronization/balancing tool for both
carburetors and throttle valve bodies. It is suitable for any combustion engine with four intake
ports from cars, motorcycles, mopeds, scooters, carts, mowers and outboard engines. The

is designed to provide a compact, easy to use and economical
synchronisation tool for home and workshop use. The SynchroKing 4S
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 four ports are used, the device will automatically ignore the sensor input from
the disconnected ports, making it possible to use the device on 2 and 3 manifold engines. The
device comes with a set of 4 of each M5 and M6 nipples, enabling easy connection to the
vacuum test ports on most vehicles
This Owner's manual must be read in conjunction with the Workshop manual of the vehicle

with the test ports in the manifolds, the idle adjuster screws and the balancing adjuster screws.
