Let me begin by saying I realzed that carburetion is vague to me. My question is how do you tune a carb for montain use? What are the fuel and idle settings. Do you have to change your mixtures every so often? I was just curious as to how this task is accomplished.:confused:

The pressure is lower at higher altitudes so less air will enter the engine. You will need to lean it out to compensate. Also advancing the timing will help too.
