On my GMC, I ve got a quadrajet carb, The truck runs real rich and get TERRIBLE gas mileage. I try to adjust the mixture screws and it doesnt make a difference. I think it might be foulin my plugs, because its starting to miss pretty bad. I messed with the timing and it doesnt help. It seems like it doesnt rev very quick either and doesnt like to have the 4 barrel kicked in. I dont know much on carbs and Ive heard bad things about these carbs. Any help would be cool. :wall:
