Showing full content instead of excerpts on posts

I am using the Chip Zero theme. Everything is working fine except what it shows of a post. It only shows excerpts with the Continue Reading button. I want it to show full posts but can’t work out what to change or where to go. I have read other forum posts but it seems different themes put the code in different places. I have tried making changes to the methods.php which is the only file I’ve been able to find a reference to excerpts and that stops the site from working at all.
