This is a updated float for all SU HS-Series carburetors, HS2, HS4, HS6. See below for instructions.
Tired of the original style floats that crack and fill with fuel? We were, too. Our new floats are molded from a modern, American-made material called Nitrophyl®, which is now specified for just about every modern fuel float. It will not crack or absorb fuel and is immune to a variety of fluids, including the new fuel formulations. Eliminate warranty issues and unhappy customers! HS carbs with the later all float and Delrin type needle.
Fitting instructions: The gap between the float and the lid face should be between 0.062" and 0.187" with the float resting on the needle but not depressing it. If adjustment is required t you will need to add a shim under the needle and seat assembly to get the correct height.
