Of course I don't. That's what I'm saying. I'm a tree guy, not a saw guy.
Well you would think if my old school saws were not in tune or constantly changing tune during the day and if I'm understanding you correctly, possibly even hour to hour, or at least morning to afternoon, once I got a couple autotune saws (now that I've had a couple for a couple years now) I would stop and think, wow this things so much more consistent running...... but I don't notice any difference. If my old school saws were running "pig rich" You'd think I smell that wouldn't you? Wouldn't it be smoking some too if that were the case? Why would I put up and ignore such issues if that were happening? No way. I buy husky so I don't have to deal with such things. I would sooner think you're running too rich of a mix or your carbs are just shot. I've never heard of a saw needing adjustment all day like your describing. No way, I'd deal with that. I always run 50:1 Stihl HP ultra and my top ends last for years and years. I have literally no such tuning changing during the day, nor have I ever had any with any saw I've run. Some old junkers, sure. Not modern, new ones though.
Oh, there's obviously something wrong with my 550. I've been running saws for at least 30 years and professionally for over 20, I do know you have to wait for a cold saw to run lol I'm not "that" ignorant about saws. Perhaps not much more knowledge than that, but I'm aware of that part. I may not work on them, but I've come to have a pretty good understanding on working with them.
This one thinks and acts like it's cold basically, if you let it set for 10-15 mins, even if you just ran it for hours on a warm day. Needs to be choked again and if you so much as look at it funny, will stall until at least 15 seconds. I've got to just take it to someone else to have looked at. It's not anything I'm doing wrong with it lol. My autotune T540 just works the same exact way my old school saws do.
