W114 280E throttle adjustment screw position

hi 
1976 mercedes W114 280E throttle ,
What should be the correct position of the throttle valve adjustment screw seen in the additional photo? How high should the adjustment screw go?
thanks for answer.
best regards

Hi Kerim,
the throttle should be totally closed and the screw has then to be screwed against the arm. It prevents the throttle wears deeper into the housing.
This screw is a sealed one, has to be adjusted once and not to be touched afterwards.

hi ,
thanks for answer. So the correct threaded screw will not rise upwards at all. Is this correct?
thanks

Hi,
this depends on the position of the arm in the position 'throttle closed'.
The 'arm' has to be in contact with the screw-top in closed position.

Maybe your throttle shows some wear - the whole unit doesn't look like to be in good condition.

thanks friend.

Hi Kerim,

Norbert has perfectly explained.
