Carburetors: SU and Zenith-Stromberg

Pair of SU's
  • Are you content with erratic idling? Resigned yourself to fiddling with your carbs each weekend?
  • Chances are good that the carburetors on your sports car have never been rebuilt.
  • Worn out needles and jets can cause too rich mixture or flooding condition. Result: Fouled plugs and premature wear on rings and bearings
  • Worn throttle shafts allow vacuum leaks which can cause a lean gas mixture and increased combustion temperatures. Result: premature valve failure
  • Worn float bowl needles can cause flooding out the overflow tubes. Result: increased danger of engine compartment fires
  • Any combination of the above conditions can spell disaster for even an apparently good running or rebuilt motor.

Rebuild & Return Only

  • For complete rebuilding send complete carburetors, but without manifold or air cleaners (linkage: optional).
  • For rebushing send just carb bodies with old shafts, butterflies, and throttle stops.
  • See also Shipping to/from Apple on Ordering Page.

Needles & Jets

  • Individually available for Zenith-Stromberg and S.U. carburetors. The most common problem we solve for our customers is richer needles to compensate for the current ethanol blended gasoline which causes the British cars to run lean. We also do custom needles for the race car folk's. Another popular item is our package of 3 to 6 of needles in a range for a particular car, which allows the car owner to dial in the carbs for the best performance. Picking up an additional 6 to 10 HP for $40 or so is a bargain not to mention seat of the pants improvement. OEM needles by necessity had to be a compromise between economy, performance and drivability in a wide range of climates and elevations. Why not optimize your car for maximum performance?
  • Most needles $5 to $18 each
