This sound counter-intuitive but try choking it.
I bought a new Husky last year after running Stihls for years. Had the same problem. Service guy told me to choke it. That solved the problem.
Let me know if that works.
If you have to choke an engine after it is warmed up and during regular use, you have a problem with your fuel mixture settings. The choke is for starting only. After it is started, it should run smoothly without the fuel being adjusted externally.
