Chainsaw Repair

Disclaimer: I am not a dealer and have no interest in Amsoil, ...

... but I have been using their Saber 2-stroke oil at the Amsoil recommended 100:1 mix. The oil mix discussion and bearing lubrication issues is interesting. The 365 I bought sight-unseen two or three years ago and, as I recall, it sounded excessively noisy when I first cranked it -- sounded like a rattle-trap -- probably bad rod bearing then. But I've burned several gallons of fuel in it since purchase without any problems or increased noise until it just seized the other day. The top end looks almost new -- no blow-by, no hot spots, no carbon at all on either the piston, head, or plug. No oil fouling. But the rod journal bearing is badly worn and one (I forget which one now, probably the clutch side) of the side bearings felt like it had sand in it. Sounds like a common problem for a variety of models.

I think this 390 I'm looking at is a 2012 model.
