Description

Carburettor Jet Needle for the 3.5L V8 twin-carburettor petrol engine. The tapered needle is carried in the carburettor piston and rides within the jet, where its profile meters the fuel flow against airflow as the piston rises and falls.

The needle taper sets the fuelling across the rev range, so a worn or incorrect needle disturbs the air/fuel mixture and running. Renew on overhaul or when re-profiling the carburettors during a tune.
