V24-0638

Note:

The limiting screw is set in the factory and must not be altered. However, if the screw is turned inadvertently set again as follows.

  • ‒ → Turn limiting screw -arrow- out until a gap exists between stop lever -1- and limiting screw -arrow-.
  • ‒ Turn limiting screw in, until it just touches the lever -1-.

Note:

To determine the exact point of contact, place a thin piece of paper between lever -1- and limiting screw. By continually moving the paper to and fro, and at the same time turning the limiting screw in, the exact point of contact can be determined.

  • ‒ From this point, turn screw in a further 1/2 turn.
  • ‒ Check throttle valve potentiometer .
  • ‒ Carry out idling check => Page 24-25 .
