When you replaced the clutch, did you also replace the roller bearing in the sprocket? If so, did you grease the new one?

 

The roller bearing only runs when then saw is at idle - when it gets worn, or if you don't lubricate it, it can pick up and try to drive the chain. It creates a lot of friction in the process and gets quite hot, which transfers to the sprocket and the chain. You can tell if this is the case as the plastic cage for the rollers has a distinctly melted look and the rollers fall out (guess how I know this....)
