Change "title" font size in header menu bar

I’ve researched and tried several things but nothing works, or im doing it wrong….

I want my site http://www.saveaca.com to say “Save ACA” in the top right corner as it is now, however I want it all on one line. If I take away the last “A” it fits.

I tried changing the title font size in the css code but it didn’t work.

If possible I would like to keep the current font size but just allow more room in the header for the text.

thanks
