I have an 8N that last fall started running rough at high idle. It got to the point that I could not use the finish mower with it because it would
start to cut out with the engine revved up. It idled just fine however. Today I decided to take a closer look. I have 35 psi compression in
cylinder 1 and 90 in the other three. I squirted some oil in cylinder one and the compression jumped up to about 70 psi. I am calling cylinder 1
the cylinder closest to the steering wheel. The engine was rebuilt by a previous owner but I do not know the details of the rebuild.
It was suggested to me that possibly the sleeve has moved just a bit and some seal has moved as a result? Does that even make sense? I have
rebuilt a few Deere's but never did anything major with a Ford. The distributor is mounted in the front if that is of any help. I do have a
service manual but it is not at my house right now so I will have to wait to take a look at it.
Any chance this could simply be a head gasket? Is my next step removing the head? Any help would be appreciated.
