Well i dont have any problems with a holley but someone before me busted the tube that goes between the bowls off so it bubbles fuel into the barrels flooding the engine on steep hills and ideling at long stops. Also the on the front bowl where the fuel line screws in with the little filter is stripped and would not tighten so it leaked fuel all over and i used one of the repair nuts and it still leaks. Tryed to get a new front bowl for it and now one can get the part anymore, including the machine shops. So im in a pickle, i need to get this fixed fast and edlebrocks are simple and a dime a dozen. If someone on here is a carb wiz and can get unattainable parts i would gladly pay you to rebuild it.
