Assuming you have the normal intake manifold supplied with the AVS carburetors, one side of the carburetor supplies cylinders 2 cylinders on the right side and two on the left, while the other side supplies the other cylinders. Your problem is more likely a vacuum leak at your intake gasket, or a plugged heat riser valve. Dick Benjamin ----- Original Message ----- From: D.
