hmmm interesting

Hi

The 1st supers in 71 had them, but they gave dreadful fuel consumption, there was a dealer fitted modification to convert them to back to single vac unit. The jets in the carb were also changed 60Z air and a 125 - 130 main from memory. The timing was then set back to 7.5 BTDC from 5ATDC. The supers that were fitted with the dual vac units had an additional vacum port at the rear of the carb facing the back of the car.
