Low compression

[Lynn Eades]

I think somewhere back there Malcolm confirmed it was a divers helmet type.
How to bend a shaft in one of those, I don't know.
As it was the centre cylinders and one half of the firing order rotation, I think I was headed in the right direction as far as a misfire goes, but can't see really why it had matching low compressions, when comp test pointed toward valves.

Good news that it is sorted!
