Anyone want to give me a quick lesson on tuning a 2 cycle carb. I'm not as dumb as I sound sometime, I have some mechanical knowledge. I know you have your 2 screws, one for air and one for fuel, right? I remember someone trying to teach me once telling me to tighten them down and then 3/4 of a turn...I dunno, something good to start with. How do I tell which one is which? Please help me out when you get a minute, its no rush. Thanks!
