wrong carb on my saw?

the 025 im starting to rebuild...has a walbro wt215 installed on it.....dont think this is the right carb....anyway to find out?...now i find where they list the wt215 for the 025.....there is several listed for this saw....i can actually buy one almost as cheap as rebuilding....do i have to stay with wt215..or can i get any of em listed for the 025?

Is the carb adjustable?

yes it is

I would re-build that one if possible? Quality should be better with this one. If its not stock it is a nice upgrade.
