Restoration Process


All SU Carbs received are subjected to:

  • A full strip down & inspection
  • Ultrasonic cleaning of all parts
  • Low pressure fine glass bead blasting of all cast parts
  • Gasket surfaces refaced
  • Bodies re bushed (where necessary)
  • Dashpots highly polished (brass parts polished where applicable)
  • All parts to be retained are checked and fully reconditioned
  • Reassembly with all genuine SU parts, full SU CRK Rebuild Kits used

In addition to the rebuild kit new needles, dashpot springs, idle screws & springs, float spindles, dashpot & float lid screws, float chamber adaptors, pivot bolts, banjo bolts etc. are fitted, this will depend on the exact carb type being built.

The carbs can be built to standard factory spec or custom built to suit the customers chosen engine spec (rolling road tuning recommended).

The carbs are returned set to the standard su start up setting and will require final set up once fitted.

A set up and tuning guide along with mounting gaskets is included with every carb.

You may think your carbs are beyond saving so please see below for some before & after pictures of what can be done. Some of these have not been used for decades!
