Billet Baseplate

The first large carb with removable baseplate. Billet baseplates on applicable Demon carbs are virtually unbreakable, unlike their cast counterparts. Air Intake

A new die-cast technique provides the most accurate method of producing concentric venturi without misalignment or shift. Fuel Bowl

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

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