Many thanks for your help. I have taken out the pistons as engine was smoking alot, but no ware lip on the cylinders. But the bottom rings on the pistons were all stuck in, i guess this could be the cause of the smoke. There is no sizes on the pistons but they are cast. Can i take it that they would be standard.

A standard bore 235 would have a 3 9/16" bore, 3.5625". Since the piston has a little clearance built into it, measuring the piston across the thrust faces 90 degrees from the wrist pin should give a measurement of around 3.561 or a bit less. Normal oversizes would be .020" over- - - -3.581, .030" oversize- - - -3.591, or 40 over, 3.601, etc.
