    Based on Years of Successful Track Experience

    Main Body
  • Die-cast aluminum
  • Optimally sized for today's engines that have improved ring seal & cylinder heads and camshafts with incredibly flat torque curves
  • Changeable air bleeds, once only available in hardcore race carburetors, offer added flexibility for carb custom tuning if needed
  • Self-contained electric choke ensures reliable, carefree service
  • Using proven combinations of venturi and throttle bore size, optimum velocity is maintained across a broader RPM range

    Metering Blocks
  • CNC-machined from solid aluminum
  • 3 stages of emulsion help break up solid fuel for better atomization at low engine RPM resulting in improved throttle response
  • Testing confirms that 3-stage emulsion is near optimum for most street or dual purpose engines
  • Stainless steel idle mixture screw with a superior nylon seal
  • Machined internal passages ensure consistent performance so original calibration remains unchanged
  • 4-corner idle system for fine-tuning

    Throttle Body
  • CNC-machined from solid aluminum (same body used in Q-Series Carburetors)
  • 3 vacuum tube connections for PCV, full manifold vacuum accessories, and the choice (off the throttle body or primary metering block) to connect the vacuum advance of a distributor if used
  • PTFE-coated throttle shafts with PTFE ribbon bearings provide smooth, low effort operation and prevent fuel migration from the shaft, such as dripping on the intake manifold
  • Mechanical secondary carbs have the Quick Link Secondary Opening System that enables rate adjustment simply by changing links (available opening rates: 40%, 60%, 1:1)

    Fuel Bowls
  • Die-cast aluminum for cooler fuel resulting in fewer fuel percolation problems
  • Sight glass to monitor fuel level without risking fuel spillage
  • All standard service replacement parts accepted
  • Notched secondary float and secondary jet extensions

    Vacuum Secondary Carburetors
  • Exclusive billet secondary housing cover
  • Cover has an integrated screw that allows timing & opening rate adjustments with just a simple turn
  • No more swapping springs to find the right combination, an adjustable housing offers much finer tuning to dial-in application

    Motor Vehicles

    WARNING: Motor vehicles contain fuel, oils and fluids, battery posts, terminals and related accessories which contain lead and lead compounds and other chemicals known to the State of California to cause cancer, birth defects and other reproductive harm. These chemicals are found in vehicles, vehicle parts and accessories, both new and as replacements. When being serviced, these vehicles generate used oil, waste fluids, grease, fumes and particulates, all known to the State of California to cause cancer, birth defects, and reproductive harm.

    Tools:

    WARNING: Some dust created by power sanding, sawing, grinding, drilling, and other construction activities contains chemicals known to the State of California to cause cancer and birth defects or other reproductive harm. Some examples of these chemicals are: lead from lead-based paints, crystalline silica from bricks and cement and other masonry products, and arsenic and chromium from chemically treated lumber. Your risk from exposure to these chemicals varies, depending on how often you do this type of work. To reduce your exposure, work in a well-ventilated area and with approved safety equipment, such as dust masks that are specially designed to filter out microscopic particles.
