I have two, an 044 with a 20" chisel point chain (I also have a 28" skip for felling big stuff). That thing hogs wood like you wouldn't believe. Then there's the 18" MS-200T with a chisel chain for climbing and lopping. Both are hot but can still take the punishment.
Huskies burn themselves up on the new gas. The only guy I know who runs them a lot successfully uses racing gas. DAMN does that stuff smell good!
We have Sinclair stations here which sell no-ethanol gas. The Honda lawn and snow machines thrive on it.
