Thank you so much Gizmo as this is the exact beast I have !!
The flywheel diagram shows a circlip in front of the captive nut which I'm going to have a closer look today when the sun comes back up. There is some very valuable info in these pictures which I haven't been able to find anywhere, but it still seems strange that there is no mention of how to gain access to the points with the flywheel attached which is obviously the only way one can set the gap correctly, anyway I'm going to have to locate 3 inch and a half or longer threaded bolts which use the same thread as the two small bolts that hold the cowling to the backing plate as that's the thread in those small holes in the flywheel, BTW any idea as to what thread they would be ? as I've found most of the bolts on the Villiers are BS sizing which I assume is the same as British Standard Whitworth ?
and again thank you so much as this info is helping immensely
Cheers,
BB
