One way to check idle AFR is to disconnect the linkage to the pump and very slowly open the throttle bodies. Ideally the idle will very slightly increase and then die. That means the AFR is barely rich. If the idle increases a lot than it's way to rich. If it dies immediately than it's too lean. This is how I usually set my idle CO. Usually works out right at 7 on the gunson.

But to do this, should i first check the throttle stops? i mean, maybe they are too much open and there is my problem...
By the way, should i remove the throttle bodies to check the throttle stops? is it complicated???
thanks!
