ill have to get back with you on that im not sure it was giving to me by a friend and we just through it on the blazer (aperantly a bad plan )

The edelbrocks are REALLY FINICKY if they get dirty. That's why I asked. The rochester's tend to flood. Check floats and choke.

The Holley's tend to blow out their power pumps, flooding the motor.

Good luck.

ahh blazer humor thats why i love my blazer i talked to my friend the carbs a cartewr afb 4 barrel but we were standing in front of the blazer last night and he did see something that might be the problem we put a spacer plate on the stock intake to use the afb carb and the lower arm of the carb is hitting the erg valve so its about a quarter open so i made a plate to go over the spot were the erg valve is and put it on the shelve since it wasnt hooked up anyway didnt get finished lastnight but should be able to wrap it up tonight i let you know and thankyou for the assist
