Does this have plug wires? Distributor?
Could be out of order.
Are you turning the engine the right way ? It shouldn’t be possible to be off 1/2 a tooth unless your belt is tearing ? Do both cams on this engine have a timing mark ? and are they both off the same amount in the same direction? When checking the marks, the belt section on the non-tensioner side should have absolutely no slack in it.
