OK, i'm an idiot... repeat after me.. "it is only by doing that you learn"..


Following Neils Post i decided to take a step back and recheck everything i have done... well, due to me being 'sure it was like this' when i built the std engine 3 years ago i had the cam about 180 degs out with the crank.
Now I aligned it properly as to the picture in the Wiki i get 3.5 and 3.3mm clearance .
So ive continued with the pistons just as flat tops.

With 30cc in the head, 1.2mm HG (6cc) and the step on one side of the mazda piston (est 1cc) i get a CR of 10.3... Camtech recommended a minimum CR of 9.. i run 95 octane petrol, so i think all should be good.
