DESCRIPTIONS OF SYSTEMS
8.1
Fuel System
The fuel injector requires clean fuel at 3 bar ± 0.2 bar with a minimum return flow of 80 liters
per hour.
Continuous circulation of fuel trough the rail removes heat from the injector and reduces the
risk of vapor locking.

Throttle Valve Setting
As a flight safety measure, the throttle valve is set to return to wide–open throttle position by
the return spring in the event of disconnection from the throttle cable.
A spring–loaded adjuster screw on the throttle body controls idle speed setting.
