Are you making sure you loosen ALL of your tensions before pulling your thread thru? Either that or you may be using, excuse the phrase "cheap" thread in your serger. Your tensions, either dials, levers or whatever must be turned right down to 0 to allow your thread to pass thru the threading channels. Hope this helps.
