QuickChange Carby:

The conventional carburetor has seen years of satisfactory service in drag racing fields. However many people only perform basic tuning of the fuel circuits provided. Most people are limited to changing the main jets and the idle mixture screw settings. By learning how to utilise the idle and transfer circuits correctly and by setting the main circuit fuel curve, engine power can be vastly improved. The problem with the conventional booster style carburettor is the time necessary to tune them and the special tooling needed to modify internals of metering blocks etc. Fuel drainage and wastage is a problem and tuning the carburettors for quickly changing atmospheric conditions could be a 20-minute exercise.

With the patent pending quick change carby, preset tuned plates can be installed in seconds. All the fuel is left in the carby. In practice it means that you can read the atmosphere at the latest possible time in the staging lanes and select a tune-up. If the racing is delayed you can reset the tune quickly.
