HIF4 carbs (AUD 616) as fitted to early rubber bumper MGBs

Parts for AUD 616 for MG M.G.B 1798 cc – SU Carburetters – SU Carburetters

This is the carb that has an incorporated distributor vac port – on later carbs this vac port removed and moved to the inlet manifold.

This change was an emissions mod that advanced the timing on tickover reducing emissions but can make it a bit lumpy and more likely to misfire a little.

Modifiers of tuned engines often prefer these carbs as it makes a better take up when the engine revs up from tickover.
