with the top cover off?you may need to tighten the head down fully before you can get the chain on.
How do I tighten the head fully with the top cover off so I can "set" the cam sprocket timing? Please forgive me for my lack of experience.I recommend you do as suggested.
No, This engine had no base or head gasket leaks. I had a buddy check things when he did the valve job.you have the head and cylinder surfaces broched/flattened?.
