I've come across situations like that and about the only thing I could think of was to pull spark plug #1, put a small rod or long screwdriver down the cylinder and turn the crankshaft pully SLOWLY AND BY HAND while I watched the rod move up or down. Once the rod got to the top and started to move back down I turned the pully backward and then carefully positioned the pully to the point where the rod was at it's highest point. I then did something to the mark on the pully so that I would know which was the indicator for #1, either a chalk mark or a little extra filing on the pully.
You'll find an idler/tensioner pulley, which rides on an adjustable arm. First you have to loosen the locknut(14mm?) of the pulley , then tighten/loosen the adjuster rod (8mm?) to adjust the belt tension. Afterwards, tighten the locknut.

There is either a tensioner or an adjustment screw on a pulley. A Haynes manual or Chiltons manual will help with the routing of the belt, and how to adjust the belt tension as well. Usually the idler pulley is used, before loosening the top bolt , loosen the center bolt of the pulley.

on the camshaft pulley there are six notches located on the inside lip closest to the block. there is a 2in pin at the 1 o'clock position when viewed from the front. each notch is a certain degree I have yet to verify.
