Its all to easy to break the rings when they are stuck but I think both of your engines were 70's so I can send some more. The bore should be 27.7mm if they are 70's.

Rocker adjusters are easy, got a few of them but don't worry if they are chipped on the edges as its just where the hardening goes right through the material. If you use the wrong size screwdriver (as someone has by the sound of it) you chip the corners really easily. It wont effect the way they operate though.

Oh the adjuster has started to brake away on the end that touches the pushrod, the slot for the screwdriver is fine.

What do you use on the rocker shaft to align the rocker centrally ? Mine has an 'o' ring then rocker, then ptfe washer in the centre. The same the other side, is this normal ?

If the pushrod side of the adjuster is damaged then its worth changing. They aren't expensive.

The configuration of the rockershaft is as you have it. The O ring seals the shaft to prevent oil leaking and the ptfe spacer acts to reduce friction. the O ring should be a fairly tight fit, if not its probably worn and needs replacing.

Bert, works for me. Put it in the stampe thread too and see how may takers we get.
