Spider - I get what 3VILC means:

 

In the big bore diagram, cyl 1 is shown as moving by 0.15" whereas cyls 2, 3 & 4 are shown to move .015" (0.015")

Is this another typo (that carries through) or should cyl one move 10x as far as the other two??

In the engine bible they are all 0.015

Yup that what I was getting at :) It didn't seem logical to move one cylinder by such a huge amount more than the others. Moving the outside 2 slightly more than the inside 2 made a little sense. To be honest, I looked at the first few posts for quite a whe thinking 'hang on, both diagrams have the same mistake!' Before I realized the arrows were different haha. Strange what the mind spots and what it overlooks

Ah, OK - now that I did miss ! Look at the detail and miss half of it !

Could be in for a rude surprise if one tried moving it nearly 4 mm (150 thousands) !

That’s how you produce the famous W series mini engine 🤪🥳😁 (I hope my smileys work)
