Hello,

Please edit the file /js/main.js.
Find the function:

function clientsCarousel(){
	"use strict";

	var $self = $('.clients_caro');
	if($self.length){
		$self.css('display', 'none');
		$self.imagesLoaded(function(){
			$self.css('display', 'block');
			$self.carouFredSel( 
			{
						items:4,
						auto: false, 

and change ‘auto’ to ‘true’.

Best regards!
