Carrington-mobile-1.0.2 size page comes in at

I have a wordpress site mobilized with Carrington-mobile-1.0.2

One of the two pages comes in at full screen perfectly. The other, when one clicks on “Read More”, comes in very enlarged so one has to reduce the size with the two finger trick.

Generally speaking, where does on set the zoom for a page? Is it in a particular php file that is standard?

Thanks,
Rocky
