spark plug issue

Did he perform the compression test correctly with the engine warm and the throttle wide open?

Screwing up either of those things would cause lower cranking compression #'s...

But it is still important to know if he did the test under the proper conditions.
It is always best to ensure accurate numbers before you move on to diagnosis.

i'll ask him, but even if he didnt have the throttle at WOT, he still has consistant numbers in all cylinders which is a good thing
