Wow, 11 pages. I haven't read past the first two.
I just picked up a Husq 562xp mkii. My Stihl 390 was stolen along with my two Makita 36v.
The Stihl was at least 15 maybe 18 years old. I bought it when my 20+ year old Homelite SuperXL bit the dust. The Stihl was very stubborn if cutting in hot weather. It gave the high rev warning when it was about to run out of gas and you had about 10-15 seconds to kill it before it died. If you didn't, that saw would fight you all the way to get it re-started. I got to be tuned in to the revs and when it sped up I knew to hit the switch. Then, fill the tank back up and start on the first pull.
When I had to shop for a new one, I read all the reviews on the new model 391. I didn't like what I read. Bad customer support from Stihl, always blaming burn't pistons on "no oil in the fuel". BS!. Add to that all the complaints of hard starting cold, not just hot. Add to that, the saw now cost $800 vs the $450 I paid way back when.
So, I started reading up on Husq. Came to the conclusion of getting the 562 xp, but read that had starting problems too. Then deeper dive into Husq message boards and everybody saying get the MKii with the re-designed engine and recalibrated AutoTune. So, I settled on that, another $800 saw. Problem was nobody, nobody, in eastern half of NC had the saw. Everyone said the same thing...backordered. I called into VA and managed to find somebody that had one. Tomorrow will be my first use of it.
