The 346XP uses as .325 pitch chain, and spins it at close to 15k RPM. I
think my confusion was caused when I switched from softer wood into
seasoned oak, things became much more difficult and the saw required
much more force to cut. After a new chain, I now understand that the
saw shouldn't require much force to cut even the oak.

Spins at 15K? You gotta be kidding?


Well, I haven't measured it, but it's somewhere around 14.5k according
to Husky. Anyway, I can verify that it's fast. But, as I've learned,
it is not tolerant of even a slightly worn chain. I think I'm going to
have to buy at least one more chain in order to make it through a day
without having to stop and sharpen.

I think it is not RPM (spinning) Chains saw generally have a
direct drive and the drive wheel is fairly small, maybe a
max of 4" in diameter (about 13" in circumference. Don't
know what your bar size and chain are assume an 18" bar
which makes the chain at least 44" long. So, divide 44 by
13 = 3.4. Your engine would be turning 3.4 x 15K or 51K.
Never heard of a chainsaw engine that could rev to 51,000
rpm. Could be wrong, but that would be one hell of an
engine.
