Have re-read these posts. My prior question was "isn't enough fuel in lo206 bowl enough fuel", meaning as long as enough fuel in bowl how could it change air/fuel ratio (paraphrased) Response was this: You need to understand that fuel gets from the bowl to the venturi by a difference in air pressure. The closer the fuel is to the venturi the less effort is required to deliver the fuel. Think of a drinking straw it takes less effort to push the liquid into your mouth when the container is full than it does when the level is low.
I appreciate the response Kart43. I am still trying to figure out if I am missing power by failing to adjust at all on carb, whether clip or floats. First, as a follow up to the response, while I understand straw explanation, isn't there a jet size that will LIMIT the amount of fuel that can get to the air for mixing purposes? Won't a "gate" or jet size or "opening" somewhere LIMIT the amount of fuel regardless if bowl is 80% full of fuel versus 50% full of fuel. In your example, isn't the size of the straw the restricting and limiting factor? Not disagreeing, just seeking better understanding.
secondly, Assuming more bowl fuel means "richer" air/fuel mixture........ what are the basic steps one uses are the track on practice/race day to decide whether to move clip or adjust float? Sound, black smoke on take off, study plug, etc? Assuming here I am at track...... what do I look at to make decision on adjustments rather than JUST LEAVE standard settings as we have done thus far? We would not be using anything fancy other than calipers for measuring float height.
Thank you Kart43 or anyone that can assist.

) . Also find you a good engine tuner with a state of the art engine dyno with accurate data acquisition systems and get to work!!!!!!!!! and as Al says install the exh temp in your test only header and generate some more useful data. The more tech data you generate the smarter you will become on proper tuning and a faster kart racer!
