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.

I love 5ci class saws. 8)

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?

I didn't even try it.

I don't blame you

You did a nice job on that combustion chamber. Im curious about the edge where it meets the top on these cylinders. When you cut .080 out of that area, how has the cylinder held up against heat?
-
Not much more than a tenth of an inch of honed chrome above where the piston normally stops on most I've worked on. Hones don't go all the way to the squish band so there can be an area of smaller dia bore towards the top.

Good thing the 288 is a single ring that's low on the piston.
