witch side are do you put the cut out grove on looking at the unit from the drivers side? help!

 

My thinking is for the flywheel to be advanced, you have to install it so that the part of the key that inserts into the crank slot is towards the rear of the bike, and the part that inserts in the flywheel slot is towards the front of the bike. Am I right

 

the cut away part faces to the rear of the bike

 

How about some pics of an install for some of us! And, as was asked, "how hard is it to spin off the key?" Thanks in advance. Ken
