MIXTURE CONTROLS

Two mixture controls are provided on these
engines.
The Needle Valve (at rear of engine)
•
When set to produce maximum power at full
throttle, this establishes the basic fuel/air mixture
strength. The correct mixture is then maintained by
the carburetor's built-in automatic mixture control
system to cover the engine's requirements at
reduced throttle settings.

This meters fuel flow at part-throttle and idling

Control Screw only if necessary.
