Most powerful demon yet

If you are looking for a carburetor that packs a little more punch than an ordinary carburetor, the Mighty Demon carburetors are for you. They feature an unrestricted choke horn for maximum air flow in addition to screw in air bleeds and idle feed restrictors. Available in vacuum secondaries or for those looking for maximum performance, mechanical secondaries and in several sizes, there is something for everyone. The Mighty Demon carburetors also feature either down leg boosters or annular boosters for maximum performance, and come straight out of the box with a ready to run tune. Simply make the adjustments you feel is necessary and you are ready to go!
