Full Page instead of Excerpt

Currently using twenty twelve theme. I’m trying to get my main page and rest of my pages to show full length, but are only showing excerpts. Please look at https://www.dukestore.net

Currently have static page set to home page and “Full Text” selected. I built this same site last year(https://www.plexusdietproducts.com) in all pages show full length. My plan is to cancel the former site when my new site https://www.dukestore.net displays correctly. Please help.

Sincerely,
Dave Long
