Открыть /admin/sources/classes/text/parser/html.php
Найти:
private $_fontSizes = array( 1 => 8, 2 => 10, 3 => 12, 4 => 14, 5 => 18, 6 => 24, 7 => 36, 8 => 48 ); и добавить здесь свои размеры шрифта, например
private $_fontSizes = array( 1 => 8, 2 => 10, 3 => 12, 4 => 14, 5 => 18, 6 => 24, 7 => 36, 8 => 48, 9 => 9, 10 => 11, 11 => 13, 12 => 15, 13 => 16, 14 => 17, 15 => 19, 16 => 20, ); Открыть /admin/sources/classes/text/parser/bbcode/defaults.php
Найти:
protected $font_sizes = array( 1 => 8, 2 => 10, 3 => 12, 4 => 14, 5 => 18, 6 => 24, 7 => 36, 8 => 48 ); и сделать то же самое:
protected $font_sizes = array( 1 => 8, 2 => 10, 3 => 12, 4 => 14, 5 => 18, 6 => 24, 7 => 36, 8 => 48, 9 => 9, 10 => 11, 11 => 13, 12 => 15, 13 => 16, 14 => 17, 15 => 19, 16 => 20, );  

Сам разобрался. 
Изменил 170px на 0 в:
.rep_bar {white-space: nowrap;margin: 6px 4px;margin-top: 170px;}
    .rep_bar .reputation {
        font-size: 10px;
        padding: 2px 10px !important;
    }
