I've just removed the backplate from an un-run Saito 62B, only to find a crack all the way across the conrod to a depth about 1/4 of the thickness. I have two of these engines, both new and un-run, so I looked in the other - exactly the fault! I contacted MacGregor but they were not aware of this issue and directed me back to the supplying model shop. Has anyone else seen this in 2020 vintage Saito engines?
