What I see on the crank pulley is 3 plastic looking things. 2 rectangular ones with a circle in the middle.

What I meant about the spot on the sprocket, is where I took the old chain apart was right where the mark on the cam gear was. But when I got the new one in, where they joined together was not at the mark.

I'll turn the engine over a couple of times, and let you know what I find.
