Anyone know the recommeneded (turns out) setting for the air screw on a
84 911? I just replaced the idle valve and the air screw has been all over the place trying to help with that problem. Now that the valve is replaced I have no idea where to set the screw. BTW it's the one pointing straight back off the big injection air flow thingee. I can set it all over but can't really discern a difference. Thanks
