Remove Excerpt and … from Home Page layout

Hi,

I tried to do this by changing these to zero:

function pinboard_excerpt_length( $length ) {
	if( pinboard_is_teaser() ) {
		if( has_post_format( 'aside' ) )
			return 0;
		else
			return 0;
	} else
		return 0;

And changing this to have a space:

function pinboard_excerpt_more($more) {
	return ' &# 160;';
}
endif;

Is there a way to truly remove it? Maybe there should be an option to check a box?
