Small saws can be very fussy on carb adjustments, I have no experience of your saw model, a new carb may sort it out but I usually persevere to the point I must change a carb rather than just doing it up front. If the saw piston is OK and it is in generally good condition, it seems likely the issue will be with the carb.

 

 

I can't say or do much more - the varying idle is a sign of a possible air leak or a leaking carb welch plug - they would be my first points to look at!
