I’m assembling my EA71 and went to put the pistons in but got confused. I’ve always been taught to put the marking on the piston orientated up. These pistons are from ETI and have the marking 0.75 stamped into them. However if I put the 0.75 at the top it is upside down? This just seems odd. Should it go upside down on top or right side up on the bottom? Or does it even matter?

Here is a page from my Haynes manual. 

 

Thanks George! That answers my question. I would have never guessed that the number will be at the bottom and right side up on cylinders 1 and 4 and will be at the top and upside down on cylinders 2 and 3.
