Stripped the block out today.
Just as well.
As the picture shows there are scores, but are not from a gudgeon pin.
So it's ready for a rebore.
all the paper gaskets kept a good seal.
Which also shows the surfaces are flat.
So I wont need to bring surfaces, just clean everything.
On removing the valves.
It's obvious the soot is getting down the guides.
Exhaust valve number 2, opened and closed when the engine was turned. But was tight on removal.
This could explain some of the symptoms, tickover was fine. But Lumpy when revved.
The water jacket had the usual crude build up.
