550XP Auto Tune question

[Jutt]

They normally adjust just fine on their own. That screw is only to be used if it can't figure itself out.

My 550 has been quirky a couple of times, usually when the temp has dropped significantly since the last use. It always figures itself out though. It doesn't like 32:1 though so I always run 40 or 50 to one.

My 562 has been flawless.

Never had hot start issues in summer weather but I do flip the choke on then off to engage high idle when restarting.

My 550 (2012) has had hot start problems on hot days, even going through the high-idle start sequence. I just curse it a few times and let it cool down while I run my other saw. I have not had the AT updated though, yet.

Just sold my 7900 and a new 562/2260 is on my short list for a replacement...

Do you use your 550 that much since you have a 562?

My 562 barely gets used, especially since I ported the 550

Ok. That's a good excuse. Send it to me and I will run it for you. I can let you know how it cuts. When you get time enjoy that saw.

Ok Duce,

Fired it up today and cut a tank of down timber and limbs. Ran great. Really a nice saw. Thanks to all for advice.
