Didn’t take the valves out in the end. Double valve springs added complications.
Once wiggles out, the camshaft front bush has an oval locating hole. So I’m now very hopeful I’ve found the knock.
I’m going to use Tony Leslie’s bolt replacement idea for the pin.
Hopefully will be on the road for the Centenary at Moreton.
This is the offending bush.
