Re: # 4 cylinder

A thought. IIRC, a few years ago someone posted a photo of a manifold where a hole had developed in the area of intake manifold below the carb where exhaust is directed when the riser valve is closed. On that manifold exhaust was able to get into the intake side. Don't remember the symptoms or know if a leak like that would only affect one cylinder unless maybe it was directed into one runner.
