Check them carefully, I believe Brad & Randy have talked about occasional bearing issues with them. That is supposed to be a mean saw.
How many hours strait do you cut wood for ,? I can pack a 660 for 4-6 hours ,But i sweat a heck of a lot less with a 440 in the same time and still cut the same amount of wood . Something to think about for firewood .Thanks Mike. I'd be looking used. Can get a used 390 for well less than a new 576.
How does one determine what date range are suspect for spun bearings?2186=385
2188=390
Thought the 385/2186 are no longer availible. Do not know for sure. In the early 385/390 days the clutch side crank bearing would spin in the crankcase often enough that the saw was not well regarded. Fairly well known for dumping bearings in general for a time, do not know these days.
The 365/372 had the same bearing issues they were more common as they sold a lot more 365/372 than the 385/390. I do not remember replacing spun crank cases on the 365/372. Just bearings and cranks.

The 385s had occasional problems the entire production run, if I remember correctly. It was corrected around 2008 with the 390XP, shortly after it was introduced.
Any idea how long of an overlap there was with both saws availible?
The 390 was rolled out in 2006 and the 385 went out in the US in 2010, methinks. Or, at least 2010 was the last time I saw a new one in a dealer. I would like to note I have never had an issue with any of the 390s on my crew from 2009-2014, when I moved out of reach of a Husqvarna dealership.
I don't know why the 385 continued to have issues where the 390 was straightened out. It may have been due to the 385 not revving as high and having to lug more, causing more extreme torsional forces. But that's just a rough guess from a civil, not mechanical engineer.
Awww I was hoping to use Amsoil at 200:1.372, 385, 390 all should run a minimum of 40:1. maybe even safer at 32:1. never had a lick of trouble out of my Mastermind 2188 that Clint (cgraham1 has) it was one bad dude.
Not 32:1? Livin on the edge Mike...I thought accountants were conservativeI'm running Amsoil at 40:1 with out any problems. That is the mix I had in Albany.

Just kidding. I like to run 32:1 with the good Husky oil in everything.
