You say he checked the timing? Was it off and if yes, how much was it off. I"ve seen timing chains jump 1 or 2 teeth which causes late valve timing. This results in very low vacuum readings.
If the timing was more than 10 degree's off and no one has touched it in a while... this could be where your headed.
Also do a compression check, lets see what psi your running in the cylinders.

The timing was off 5 degrees when he checked it and he set it back to 6 degrees. The compression check shows it's running at 135 pounds. It doesn't vary within 2 to 3 pounds in each cylinder.
He said tonight the only thing he hasn't gotten down to and checked with the valve adjustments. Could this have something to do with it? Motor was rebuilt 3 years ago.
