• Adjust the throttle stop screw so the engine runs at a fast tick-over, say about 20%
above the idle speed you wish to achieve
• Unscrew the pilot air screw to increase the engine speed to its fastest possible.
• Gradually unscrew the throttle stop screw to reduce engine speed to the target idle
speed
,BR>
• Again unscrew the pilot air screw to increase engine to the highest tick-over possible
• Finally, gradually unscrew the throttle stop screw to reduce engine speed to the correct idle speed.
(Usually this process carried out twice – as described – will be sufficient to achieve a correct tick-over.)
NB – sequence: pilot air screw out = fast; throttle stop screw out = slow
