Chainsaw Repair

 Well I've been running everything I own at 32:1 regardless if any manufacturer says 50:1, 50:1 just seems way to light on oil for something spinning the rpms of a chainsaw and the likes.
 I was afraid that the bearing failures were do to cheaper bearings in the newer saws.  I own a 2012 husky 390xp 28''bar, I've only cut about 30 face cord with it but love the saw, I was thinking of adding a 372xp with a 20'' bar to my collection.  My old 51's run fine, but as you know, are not in the same league power wise.
