    Quick Fuel SS-650-AN - Quick Fuel SS Carburetors


    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
  • Teflon-coated throttle shafts with Teflon 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
