What is high speed full power circuit

This circuit can be called the latter half of the high speed part load circuit. In this more than half throttle opens. As a result, air goes into cylinder through air horn venturi with its full velocity and pulls more petrol in the same proportion. The mixture obtained at this ratio is capable of running the engine to its full capacity. For preparing more powerful mixture, petrol is controlled by a metering rod and a jet. This metering rod is made in stap and is directly linked to the accelerator. When it rises up, the quantity of petrol increases.
