So i have an edlebrock 600 carb, its been rebuilt and cleaned and taken in to a shop for the jets to be adjusted along with the distributor timed. Drove fine for awhile even a few hours in the bush to go camping and back drove just fine lots of power. Now it won't idle, it starts but then dies right away, my step-dad adjusted the jets a bit to idle but it is soo rough it shakes the hole car. My step-dad thinks it is a carb issue and we need a new one but i am open to ideas. Almost feels as though it is out of gas but you can clearly see gas in the fuel filter.
