CNKS,
The exhaust plenum in the intake manifold is not connected in any way with the intake runners. If it were, the engine would be recirculating exhaust and not run at all. In some defective manifolds that have rusted out, the problem is hidden in that "well" like area and hard to find. If it were connected hot exhaust/sparks would ignite the intake mix before entering the cylinders, providing a great backfire. Heat is the only contribution that part of the system adds to the tractor, and that is to enhance vaporization when cold. Good luck, JimN
