Application
The SynchroKing 8
is a universal vacuum synchronization/balancing tool for both carburetors
and throttle valve bodies. It is suitable for any combustion engine with up to eight intake ports
from cars, motorcycles, mopeds, scooters, karts, mowers and outboard engines. The
SynchroKing 8
is designed to provide a compact, easy to use and economical synchronisation
tool for home and workshop use. The SynchroKing 8
is primarily designed for use with engines
with eight 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 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
before using the SynchroKing 8
. Before proceeding the user should as a minimum be familiar
with the test ports in the manifolds, the idle adjuster screws and the balancing adjuster screws.
