Ignition timing issue, very strange...

Okay so we decided to do my first gen for ignition timing in class today, evering was very strange...

we figured the leading first rotor spark plug should have been where to hook up the timing light. We tried to use the book to work on it...

but it seems that the leading mark barely appears at 180 degrees advance! Either the pully was installed 180 degrees backwards or we're doing something wrong.


Any help?

We were trying to do that as per the book...

But the problem we have is that the timing light will not show the marks until 180 Degrees Advance and even then its still has a bit to go.

The engine runs normally though so we have no clue what the hell is wrong with it...
