You are not an idiot. There isn't one there. <br />If you look down at the squareish float chamber on the carb, down beneath where the low speed adjustment comes into the carb, you'll see a plug threaded into the casting. It looks kind of like a bolt. If you remove that plug, behind it is a fixed oriface that you can unscrew and replace with a larger/smaller one to compensate for altitude.<br /><br />Hope that explains it!

You are no idiot and your question is a good one. A lot of people, including myself come here to learn. Your motor may well not have a "high speed adjustment". Evinrude/Johnson started introducing carburetors in the 60's that have a fixed orifice. This fixed orifice is located at the same place the high speed needle would go which is at the bottom of your carburetor bowl faceing toward the front.
