I have an edelbrock intake and carb on my 350 and my trucks running a bit rich and is spitting carbon from the exhaust, what is the exact readjustment ratio procedure for the carb to put it back to normal? I do not know what it is at right now. And what cleaners should i run through my truck to get the system cleaner?

There is no exact setting. All carbs are different. What I always would do is turn both fuel and air mixture screws in the entire way and then back out 1 1/2 turns. From there, I would adjust slowly until the engine runs its smoothest.
