I've a purple head CMB .67 and I'm trying to figure out which way the piston goes into the cylinder. The skirt is larger on one side (below the wrist pin) and there are a couple of small holes on either side of the wrist pin, part way round. looking at the opposite side, the skirt is smaller and the holes can't be seen. Which side should be facing the exhaust port?
