GV125 with a GV250 carburetor

Hi! I have a 2004 GV125 to which the previous owner has mounted a GV250 carburetor. I have to do maintenance on the carburetor and I wanted to take the opportunity to bring it back to how it should be without buying a new carburetor. Is it right to put a main jet and a pilot jet with the measures of the GV125 on a carburetor of the GV250? Is it better to let it go? Thank you
