Hi All Thanks for all the help so far, having removed the adjuster and measured it, the outside diameter across the thread is .297 inch (5/16 equates to 0.3125) and the head of the adjuster and locknut fits a 3/16 Whitworth spanner! The TPI is 26, so I assume it is a cycle thread. Have I got this co...

Thanks for everyone's replies, a bit of dismantling and further investigation is needed I think, nobody likes the idea of welding so I will cross that off the list. Thanks for the thread information.

The oil line from crank case to head is just visible to the left of the magneto adv/retard cable. It doesn't seem to put a lot of oil mist anywhere and ...

Thanks for the photos, I will have to take some closer pics of the top of my head, it seems to have the holes but not right through. There is an oil feed from top of the crank case to the rocker box but it is a single union and doesn't push much oil mist out, I've left the tappet covers off so I can...

Thank you all for the quick replies, order now in with draganfly.

Thanks very much, this is my first Ariel so a steep learning curve!
I'll see if I have the inlet side on a picture as well.
