The tentioner pulley must be tight, before you pull the pin on your tentioner. The two pin holes on the outside of the pulley, should be at 11 and 1 oclock, To at least get it good and tight. If, your balance shafts are out you dont have to line that up at all. Idk
Make sure both cams can even line up, you might have to turn just one cam before you put it at tdc.
