What is EMS?
Electronic Management System
ENSURES OPTIMUM ENGINE SPEED UNDER ANY WORKING
EMS automatically monitors engine speed and fluctuation.
In order to ensure optimum cutting performance, EMS
automatically controls fuel supply by repeating full throttle and
idle operation when needed.
ADJUSTS TO WORKING CONDITIONS
EMS ensures optimum engine performance regardless of the
altitude, fuel type or filter condition.
When working conditions change, the micro processor in
the ignition coil sends an electric signal to the carburetor to
optimise the engine speed.
