Control Jet System
Your engine is equipped with a unique system enabling improved acceleration from idle to high speed. This system allows the mixture to be
controlled while the throttle valve is opening. It will lean the mixture at low rpm and at idle. Conversely the mixture will become richer as the
throttle is opening. This system provides better acceleration to high speed and maintains a stable idle.
This system was developed for the Evolution 152cc engine. It is recommended that you do not change the mixture control leverage.
