smh,welcome to the forum.Good luck with that Husky 61.

Thanks! Using info I learned here I did do a 272 'upgrade' (p&c) & muffler mod. The only deviation was I used a hs-224 carb, instead of using the factory 272 hs-260. Reason being I didn't want to hack-up the stock '61 top cover. And, I guess, using the -260 there was that possibility (different filter set-up)? I dunno, but this worked nicely. One question: Does anyone know if there is a performance penalty for that substitution?
In any case, the saw started third pull, runs great. A minor carb adjust to the L seemed to help in the lower rpms. That's all I did. Did I mention it runs great :-)  And a noticeably deeper exhaust tone, too.

Post pics! I did mine (1978 vintage 61 with a low profile white cover)  and hacked the cover for visual effect more than anything else. Mine was the older style cover so it didn't clear the fins or the spark plug. I posted its build around here somewhere a couple of years back. Its a solid and practical build....they do respond well to certain muffler mods in my experience. Also the old style intake horn and filter can be hogged out and seems to match the later 272 versions (posted pics of that somewhere too)..at least the saw performs well enough you can't really tell the difference vs. my more normal 272's. Did a 266 as well last fall....same thing. Solid performer. Love this 200 series line of saws to hack around with, glad you (And others) have rediscovered these and having fun with them.

I agree on all accounts, weimedog. Until I got into these saws I didn't realize how 'Chevy-like' Husky's are. Meaning that, within the various model runs, you can mix-and-match components to your liking. And that makes tinkering easy and fun for the average Joe. That's just plain cool.

So, the attached pic shows the '61 in midst of teardown. ...oops, either I'm disallowed from uploading or I just don't know how. Sorry, no pic :-(
Anyway, the best metric I have to gauge total usage is by number of chords over its lifetime; I estimate 200 chords of wood in 10 years, which I believe is realistic, if not conservative.
The piston and cylinder are both B grade". The piston fits snug in the bore. Using a cheap digital mic, I measured .002-.003 p-to-c. The factory cylinder crosshatch pattern is still visible on the wearing surfaces.
The piston wear pattern is light, imo. And, despite a steady diet of 25-to-1 oil mix of various pedigree, there was minimal carbon, the heaviest of which was in the exhaust port. The piston top and combustion chamber had almost no carbon, more like soot. The cylinder ring has slight blackening on parts of the ring, no carbon in the ring land.
I guess that's it.
