catwingz on "[Theme: Quark] customizing list with bullet image"

I have given custom bullet images to other themes, but this one is eluding me. The page of the site being developed is at http://catwingzworkshop.com/services/
The list items are supposed to be preceded by a 16px image. I have an undesirable background color in the style for now to let me know if I have established communication.

The CSS has changed many times, but the current style is:

#post-12 ul .bullet {
	list-style-image:url('http://catwingzworkshop.com/wp-content/themes/quark/images/puzzle-bullet.gif') no-repeat;
	background: #ccc;
}

Can anyone spot what I am missing? thank you
