Floats have two adjustments. One is the "level" it adjusts the level of fuel in the bowl when the carb is full, and shuts off the flow. this acts like a toilet tank float and when in continuous operation running the tractor, is just part way open allowing just enough fuel in to support the flow into the jets and idle ports. It is the distance from the float to the carb body. (usually measured with the carb upside down, or with finger pressure and good "feel" with it on the tractor. The second is float drop. most carbs have this adjustment. It stops the float from dangling too far when the fuel stops coming in (out of gas), or the valve is shut off. The purpose is to prevent the float pontoons from touching the bowl (ever). if they touch, they can stick and prevent control, or just wear and eventually get a hole that sinks them. The pontoons must also be adjusted some times to assure they do not scrape on the sides. Jim
