looks like it spent a lot of time milling prior to getting passed onto the pawnshop. Maybe it never got the heat up/cool down cycles it needed? I'd like to find an 066 like that to build for myself though.

That's entirely possible. I've seen a few 066/660 & Alaskan combos around town.

Geez, Brad.....I missed this post!

You're on another roll, for good and FREE deals again!!!:chainsawguy:

That's an ugly piston failure for sure......A real decent looking project though. :clap:

If the deals come together, I've got some more saws lined up too......Got two more yesterday too. :rock:

Yep, that it is a classic cast piston failure when you have excess clearance.

With the amount of dust inside the saw, I'm amazed it wasn't cooked, bad.

I siezed a saw with a lot less crap than that. That dust looks a lot like one of two things we occasionally see in MN...when a red oak dies of internal fungus rot, you'll bring up a cloud of fine red dust like that when cutting. Same thing when cutting up old cedar utility poles for fence posts.

Since Oak isn't common where Bmorgan is from, I'm guessing pacific coast cedar? And a sawyer that didn't have access (or desire) to an air compressor. There's red dust on the piston: is that settling on from the outside, or did the air filter fail?

I see red dust everywhere in my part MN. Fortunately if your saw is anywhere near it you are probably mentally incapable of operating a saw:monkey: We got iron ore dust on everything but not in the trees.
