I need help finding the idle adjustment screw on my 93 ga16de. Where the hell is that thing, I looked in the haynes manual and it does not tell me where it is, it shows a pic but not big enough to tell where. I think I may have found it but wasnt sure if that was it or not and didnt want to screw anything up. If you know please give me detailed directions where it is at. By the way, these forums kick ass, any problem I have someone can help. Thanks for everything!
