Agreed, I have never seen an engine yet to have the baffle on the wrong side other than these four. The weird thing is that they came from different sources, two from one, two from another (not Ebay either) and one of them was new. Bizarre. Why anyone would swap them around like that is beyond me. The cylinders are in the correct orientation, That was the first thing I checked when I got them.

Downunder, appreciate the tip re the conrod.
