| The BlackJack Carburetor is a high-flow
performance carburetor designed to be user friendly utilizing a proven
annular discharge design with modified internal circuits. It consistently
offers instant throttle response without loading up, even after prolonged
periods of idling. The BlackJack Carburetor incorporates a flow bench
designed, CNC machined billet air velocity stack with a true venturi
providing more precise high speed transition. There is no booster
venturi or protruding nozzle tube to restrict flow. (Tests have shown
the addition of a nozzle tube will decrease flow by as much as 9%)
