saw dies out when revs should reach full revs

Remove the exhaust and start it without it fitted and see if it's any different. If it is, then (if it has one fitted) clean/replace the spark arrestor within the exhaust, or if not replace the exhaust as a whole. If you don't want to do any of that, then light a fire and throw the exhaust into it for a few hours- this will harden the carbon build up and can be easily tapped out when cooled.

Neither will mine. I have: rebuilt the carb., put in a new fuel line and filter, a new spark plug and air filter, checked the pulse port, cleaned the silencer. I think that the next ploy will be to pitch it into a skip. Good luck with yours, I will keep an eye out to see if you succeed.
