I may have to set my idle down slightly after they install the electronic ignition. Warm it is idling around 1500, 1600. These pictures look like throttle cable to me but I don't see any adjustment screw on this.

QUOTE(brcacti @ Feb 1 2020, 07:08 AM)  Thanks for the information, so what would be an ideal cold and warm idle speed ?? can I suggest the following? 1. remove the throttle cable 2. if AAR (auxiliary air regulator) is working well, meaning at initial cold start, AAR is open and the engine should run more than 1,200 rpm and when it gets warm (AAR will closed) rpm should be around 700 and 900 rpm If AAR is not working well, just make sure it is closed and only just play with the throttle to let the engine warm. 3. If engine is warm already, adjust the screw nut on the throttle body to get it around 800 rpm. AAR at cold engine should be open to give some air (like a vacuum leak) and makes the rpm higher and when engine is getting warmer, AAR should be closing and air is decreasing while rpm goes down. |
