Default Re: No. 7 Cyl never gives evidence of a power stroke on '46 Flathead

I saw a 48 in the shop that was doing the same things. After pulling the intake it was obvious why; when prying against the intake port for that cylinder to release a valve guide clip, someone broke off a chunk of the port at the manifold surface. It was sucking out of the crankcase instead of thru the manifold.
