Ok, I got how to set it. But will it choke by itself during a cold start or I have to choke it from the interior (ie press the gas). Also, to set it I am assuming the car needs to be cold. What parameters or guidelines do I need to look for when setting it? Will I see the primaries close?
Yes, you have to depress the gas pedal all the way at least once(3 times does it for me). The primary air flaps should close, but not super tight and not all the way. 80%-90% is a good starting point. In a previous post, there is a good schematic of the system. In it you'll find the fast idle screw, its buried under the linkage area. You should set that at about 1500 rpms. You only get one shot a day at this so double check everything before you pull the trigger. Once running, after about 1 minute, tap the gas it should come down about 200-300 rpms, around 1100 to 1200 and the idle should stabilize. This is all I can think of now, let me know how it goes!
