I did remove the cam gears. I aligned per my picture and per the instructions. Enya's have a small dot on each gear and two groves on the crank. Aligned how they should be, valves opening in the right sequence, just compression in the wrong directions. So either it is a clockwise turning engine (doubtful), or it has to due with the crank and the piston arm. I'll take it back out tonight and see if flipping the direction of the piston arm to works.
