I have never looked at one of these before so can someone confirm that some moron put them on the wrong side or am I the moron cause I yet don't understand how it works. All the pics I found of them on this site show them on the lobe side, and I can not even reason how they would work like they are now. If they are on wrong side is it a matter of taking them off and putting them on other side? Can they be switched by dropping the pan or does the cam have to come out? Attached is a pic but hard to see anything. Thanks clint

Your picture sucks so I am not sure I even understand your question, but here are some pictures of a Kohler cam with ACR. As far as how it works, the little square nub (highlighted in red) holds the exhaust valve open a little bit at cranking speed to relieve compression. When it starts, centrifical force flings that arm out of the way and lets the cam lobe open the valve normally. The spring is there to counter act centrifical force and hold the ACR in until it starts. I don't have a clue how anyone could put any parts on the wrong side of the gear as you are decribing. Hope the pictures help.
