Setting the float on a 2100 is fairly easy, but different people have different ideas as to what is the best method. It’s best to set the float on the Jeep with the top cover removed and the Jeep parked on a flat spot with the engine idling. For a Jeep that gets used off-road, our friend Shane recommends measuring from the machined edge at the top of carb body down 5⁄8-inch to the top of the float. Brennan showed us a quick on-trail method to set the float for off-road use. Use a quarter as your measuring stick and measure from the top of the machined surface at the top of the fuel bowl to the fuel level so that the bottom of the quarter just meets the fuel in the bowl.
