It’s pretty easy, #1 is at the rear, it’s marked on the cap, make a mark with a sharpie on the cap seating ring of where #1 is on the cap, turn the engine over by hand (I forget the size, 13/16 or 21mm I think) until the rotor points at #1and the crank pulley points at the 0 position on the timing pointer-left lower of front of engine, if it lines up with the distributor cranked balls-deep, then yea, it’s out a tooth or two. Remove and reset it in the correct position, hold down for the distributor is 1/2”.
