I have also spent ages pouring over this problem. It’s obviously important to make sure that all the files are linking to the correct places (ie the various CSS and JS files needed), as well as the images. However, in the end I identified my problem was that jcarousel didn’t like the css and js call ups going in the header, in fact I put everything in the main body, in my case straight into the index.php file. Ie I have nothing in my header.php file for jcarousel, it’s ALL in index.php.
Hope this helps!
Best
