You're correct, I meant 029. Thanks for all the advice.
I had a neighbor that was vehemently against milling with chainsaws as the would "burn up". Was always a bit skeptical as his reason was they are air cooled and running on their side so could not cool. I mentioned they do have a fan, but he insisted they would burn up.
By rich, you mean tuning or more oil in the mix?
Saws can definitely burn up if you run lean - ask me how I know
Run your saw rich to prevent this, as Fordsoll says. This consists of two things: (1) Use extra oil in your mix. Husky recommends 33:1 but you can use 40:1, and (2) tune your H jet to a few hundred RPM below max recommended RPM. My saw's spec says 12.5K, and I've tuned to 11.8K or so. Note that adding extra oil in your mix makes the carb run leaner (since there's now less fuel in the mix) so retuning is essential
after switching to the new mix.
After doing this, I've noticed that my cylinder temps (as measured by an IR thermometer) never get beyond 280F, even on a long cut (e.g. a 15-ft 6x6 done the other day). For comparison, 2-3 cookies from a large tree would get my cylinder to 220-230 or so.
So I'll add: get a feel for your saw temps and monitor them. Let idle between cuts and even every 3-5 feet if you're paranoid like I am.
