Reply To: 1961 40hp Evinrude difficult to turn under compression

Thanks for your reply.  Let me just say, I am new to this so I am not sure what normal is.  My model is 35525.  I have been searching and reading everything I can.  I am not a hulk but it seems like the resistance is stronger than it should be.

I pulled the cylinder head but that only allowed me to see the tops of the cylinders and the bore walls.  I have not seen the crank shaft or cam.

I just looked up the “what and where” of the valve you mentioned.  Is it in the cylinder head itself?  I didn’t see it or check it when I changed the head gasket.  Do I need to take the cylinder head off to check it. How do I know whether it is functioning properly? In the diagram it looks like there is an o-ring as well associated with it.

Thanks!
