How to set timing/install timing chain on CB175

[Crim]

So I'm in the process of rebuilding (new pistons + rings) a CB175 engine, but I'm stuck on re-installing the timing chain.

The manual says:
"Align the 'T' timing mark on the generator to the timing index mark."

So finding the T timing mark on the generator is easy enough, but I have no idea what the timing index mark is?

Also the manual states for the camshaft:
"Position the camshaft sprocket so that the 'O' mark on the face of the sproket is at the top"

I cant seem to find any marking on the cam sprocket.

Any help would be awesome!
Thanks,
Stephen.

so I found the timing index for the crank, but I'm still at a loss with the camshaft...

and I found the little 'o' stamped on the side of the cam sprocket, by god that is the smallest/faintest little o I've ever seen

So I've got the motor all back together, I sure hope the timing chain is correct.
