JJrider, You were right about really having to loosen up the gaps,
I have reset the gaps again, and she started easier and ran a lot quieter, then I found two manifold bolts were loose, sorted them and she is now
I still have this slight metallic tapping at the top (valve cover area) but Hey-Ho I will live with it.
I used a great xt forum in oz (can’t get connected now for some reason)
so I am really pleased to find this forum.
Many thanks for the input gents, it is really appreciated.
