RE: RCG 15 CC Cylinder rotation
Neat. Picture of it running pretty much confirms it can be done. I was looking at the owner's comments, think there may be a typo. He's saying he turned the cylinder 90 degrees, then later says he turned it 180 degrees(?). I think he meant to say he turned the piston 180 degrees - so the ring end gap would work out - without snagging a port opening?
Rear exhaust not popular? That's a little out of touch...
