Any reviews of the 181? One has popped up on local craigslist.

I think they are a good saw. Nicely built, firm feel in your
hands, not too heavy. The cylinder cover is a bastard to put
back on because of the throttle link and the air filter boot.

Nothing wrong with owning that chainsaw. That would be a good
blocker.
But it has been messaged a little bit.

Saw looks strong. I may have to see about getting that one on
craigslist. Same bore and stroke as a 681.

It's a little messed with, I cut 0.040" out of the squish to
make a 272 piston work in it. They have a tiny combustion
chamber to being with so I had to cut the camber wider to
increase the combustion chamber or it would have pull around 260
psi. It currently pulls around 220 psi and has a nice
combustion chamber shape.

Yeah that is a tiny chamber. It may be a fun saw to play with
pretty cheap.

It's hard to see but there are two angles besides the squish
band that I cut in there to smooth out the turn and to enlarge
the combustion chamber. Not the worst I've had to do, I had to
cut three angles on my 288 after taking 0.080" our of the
squish.

Did you have 300 lbs of compression on the 288 before you opened
the chamber?
