Thank you, Peter for this. Like many I suppose, I added a tooth to the engine sprocket for a smoother and more relaxed ride and in London traffic I found the slightly higher intermediate gearing of my VB was an advantage and the change in top gear of little consequence, but I found that out on the o...

"Saw thro' the spindle on both sides" and "burn out the rubber" was what I was driven to, too. May I suggest that the replacement parts be stainless steel as offered here https://acmestainless.co.uk/product-category/ariel/ariel-swinging-arm/?v=79cba1185463 to reduce future diffic...

Thank you for that, Steve.

If you have December 2020's "Cheval de Fer" you'll see that there's a plea in the "Wanted" section from Tony Regan for accurate dimensions of the VB tappets even a worn out pattern so copies might be made. Can anyone help? (Alas, I assembled my own VB with my less than perfect ta...

Today I tried tightening the setscrews in various patterns and at various tiny rates while rotating the engine in the hope that all would settle satisfactory, but each time at the final tightening the tappets stuck and the valves were kept off their seats. The tappets remained stuck (i.e. could not ...

Hmmm,
Thanks for the advice Paul. The components all came out of the engine some years ago and the magneto plate bolt is loose. (I'll take more care about that.) I'm wondering about distortion too. I'll try doing up the setscrews in a different order.
Thanks again, MikeN.

On the camshaft, yes Dave, some 5-10 thou. I fear there's none on the cam follower pivot pin - but no idea why! If I'm right how could that happen?
