yes i searched.... i never thought i'd own a carb'd vehicle but my new 78 bronco has an edelbrock something on it... its a POS, tiny little off cambers/hills and it dies right away... i looked around and a lot of people like Qjets and truck avengers... but since i know NOTHING about carbs i figured i'd better ask and figure things out for sure... i dont know if its vacuum operated secondaries or not, hell i dont even know what the hell vacuum operated secondaries are... im a diesel guy. this stuff confuses the **** out of me.... what kinds of carbs are out there? what kinds of secondaries? what makes a good offroad carb? someone help me please... here are pics of whats on it... oh and its got a vacuum leak. (so im told anyway) once again, im not used to vaacuum, only boost pressure. how the hell do i find a damn vacuum leak?
