I had a Craftsman /poulan in the 90s that would not restart after 1 tank of fuel..vapor lock..A properly tuned 2 stroke will sputter under no load.
Under load, it will smooth out and produce peak power.
I wore out a few saws back in the day.
Honestly, the best I ever ran was a craftsman branded pouland back in the early 80s. It came with a 20" bar and chain.
Once that wore out I put an 18" set on it. It would cut hard heart mesquite like nobody's business. I let it go at a moving sale in 06.
I threw it over a hill in Shackleford County while working on a hunting lease and I guess its still out there
