Re: Exhaust to intake connection - Poly or 57/58 Manifold

Also be aware that the divorced choke poly and 57/58 manifolds have two small bolts to hold the choke assembly into the "heat cup" on the manifold. If these have been tapped, you need to plug them with exhaust sealant and appropriate size/thread allen set screws, since they are through-drilled into the exhaust crossover passage in the manifold. Otherwise, you will have an exhaust leak around the carburetor, and might not figure out quickly where the noise is coming from!
