Description

Genuine SU waxstat carburetter jet assembly that has an an all-metal boss with a copper stat underneath which weakens the fuel mixture for greater economy on motorway type journeys. This is however prone to sticking open especially if using with an LCB manifold and no heatshield. It is fitted to later Mini models with HS4 1.5 inch single carburetters from 1975 to 1990.
See below for a kit to convert back to the old type of jet.
