Turn the throttle lever so that the damper rod extends to its full length (released lever (A) and touches the screw (B).
Close the throttle lever until the screw (Z) touches the released lever (D) - the high idle speed adjustment screw.
Check the engine speed at the moment when the damper starts to work and compare with the required values (1800±200 rpm).
If necessary, adjust with screw (B).
Release the released lever and check that the engine speed slowly returns to the desired idle speed.
