I changed the chains as the engine had 'died' on me. They were stretched badly and the two guides were wrecked. I had hoped that was the cause of the problem.

I know I can drop some oil down the plug hole and see if this brings the compression up. But what I really need to know is should there be a gap between the follower and the bottom of the cam? If not, then it looks like all the inlet valves are bent. But its a bit strange the gap is consistent
