Welcome aboard! Do you know if the saw has been sitting for a long period of time? The Zama carburetor is not difficult to service, disassemble it in a wash tub so you don't lose small parts and clean it thoroughly. The overhaul kit is p/n RB-149. You will also need to replace the fuel line if it is spongy or brittle.
