    Billet Baseplate

    First large carburetor with removable baseplate. The billet baseplates on all Demon carburetors (where featured) are virtually unbreakable, unlike their cast counterparts.
    Air Intake

    Offers a new die-casting technology, which provides the most accurate, repeatable method of producing concentric venturii without misalignment or shift.
    Fuel Bowl

    Demon float bowls are supplied complete with sight glasses, which permit float level adjustments without the risk of fuel spillage.
    Metering Blocks

    CNC-machined metering blocks from billet aluminum prevent porosity and variations in the metering circuits
