Setting mixture another method

This thread http://forums.pelicanparts.com/showthread.php?t=437101&highlight=CIS+rich has this info on setting mixture.
"right to richen (CW). always turn it from lean to rich for final adjustment. if you do not have a way to check CO, here is how i set mine. turn it CW until it surges at idle then back off a tad. blip the throttle and if the RPM's dip down then come back up to idle, it is too rich. turn it CCW about half a turn then back CW a little less than how far you turned it CCW. blip the throttle again. repeat until it no longer dips down when the RPM's come back down. mine is set so it has just a hint of wanting to dip down when i let off the gas. drive it and check again. i later had mine checked and it was dead on 3%." by T77911S

CIS mixture adjustment method

This post Its time again! on page 6 has info on the push/pull method, and on checking the AAV. Air leak, pull the valve off, plug the hoses, does that make any difference. Free up the inside of the valve itself.
