New 562 xp

AutoTunes do not like excessive idle time, as Rich stated it can throw off the fuel curve. My professional advice is beat it like it owes you money. They are like an old two stroke Detroit Diesel, the harder you beat on them the better they run.

I appreciate the posts.
Very good to know about extended idle time.

I questioned how long idle time would be, before actually trying that, I timed what I do, run time/down time.
Run times to cut two 100" logs into six rounds each was less than two minutes, average closer to 1 min. 30 sec. (Five cuts, walk around splitter, five more cuts.)
Down time was three to seven minutes, depending. That's splitting and repositioning logs to be cut, brushed off if need be.
I never idled it while doing that.

I did idle it before shutting off, and that has helped starting immensely, as long as the decompression is not used.
I only did a little more than half a cord total and it wasn't that warm today.

I am encouraged however, and again, greatly appreciate all suggestions, comments, and the latest offer.

As to running strong for five minutes, I would if I could. However, I no longer have access to any large wood to do that with, and the largest compatible bar I have is 20".

What I do is more like limbing, as far as throttle, and run time.
Which I assume is what this saw is for, and maybe bucking mid size logs.

Tomorrows another day...
It was starting on high idle, no decomp.

These are professional falling saws they’re made to run hard bucking and limbing are pretty easy on a power head vs actual falling duty. Take a face like I pulled out of that cedar to get that popped out took 15 minutes probably with a few minutes in between of popping wood out with an axe. When I’m cutting I don’t idle a saw very often it’s get to work till the job is done that means full throttle to finger off the trigger to shut off the saw. If you say this is hard on them so be it but we use to figure on replacing them once a year it was a cost of business.

Cut cookies with it wide open throttle for 5 minutes. You shouldn't have to do this more than once.

As much as I agree with you guys about how to get a husky autotune saw to run/calibrate correctly....... I don't think it will make any difference with a vapor lock. Try some truefuel and see if you are still having the problem. Also your dealer should be able to tell you what your stats of the saw are.... Like carb temp betting it is a higher then normal number. My brother has a 555 and has never had a hot restart issue.

I run straight pump gas it has 10% ethanol included without an issue. Now that said is fuel the issue possibly but also not likely if it was don’t you think your vehicle would also be having some issues?

Ha, stayed in a rv park in East Jordan by a blinker light in town. We made reservations and wanted to be near Charlexvois (spelling), having never seen the rv park. There was a baseball game till 1:00 am with loud speakers and full lighting 500' away, and trucks with exhaust brakes slowing to the red blinker light, and then gearing up, all night long. Beautiful area though, and Margaret found an Alpaca farm, processing wool place for spinning. There is a foundry there, and I assume they make manhole castings and covers.

I'm using Stihl HD Ultra mix.

Frustrating day so I took a break from regular cutting. I did clear some limb blowdowns on trails next door at a nature sanctuary with the 021.

I did wonder if I could remove the 562 black badge on the top of the cover, revealing some vent holes.
Or run it without the cover.
But, it's a brand new saw...

$750.for a saw and tax. It sucks, and I'm having a hard time moving on from it.
It's not even the money.
I don't even want to look at the saw.
If I can't start, and finish, the day with it... it doesn't rate a place on the shelf at night.
Would you drive a car like that?

Agree, the money is one thing, but at this day and age you would think
someone could make a chainsaw that would start in all weather and just
get on with it.

EDIT , Just told Dolamar make such saws, and Echo.

I would not suggest letting the Auto Tune saws idle excessively. They will over correct and become sluggish if left to idle for a minute or two. Excessive partial throttle operation will throw off the fuel settings as well. Joe @Onan18 please chime in here.

Like Steve said, run it like you stole it for 5 minutes. If you're still having issues your dealer can't solve, I'd be happy to hook it up to the service tool and give it a once over for free. You'll have to cover shipping here, I'll cover the ride back. This 562xp should be one of your go to saws.

Helluva offer there. Good on ya![/QUOTE]
Very decent offer there, the OP should take note how often good support
is mentioned, it’s priceless when things do go wrong.

Fuel injection has a return system so extra fuel is returned to the tank to cool. Two lines going to and from the tank usually. I also noticed when I replaced the fuel filter on my f150 last week the lines are wrapped in insulation in places where they would potentially get hot near the exhaust/motor.

 

[huskyboy]

Older carbureted vehicles can have problems with vapor lock in the line just like saws can. The real problem is today’s pump fuel. I have a feeling the epa knows this... they want to get rid of carburetors. It’s not really rocket science to figure this out. I think they are trying to put purge bulbs on saws purposely to give the option to help purge cool fuel through the carb. But that only really works if your fuel is cool in the gas tank. Which in some saws you’d be surprised how hot the gas gets in the tank sitting in the sun. It ain’t nice and cool like it is on your vehicle where it sits in the undercarriage.

This discussion and help has taken the edge off the frustration side and focused on the possible problem.
Thank you for that.

My initial response to the issue was operator error, and getting to know how this saw functions.
When to choke, I automatically used decompression hot or cold, high idle starts, etc.
Then I suspected the fuel. The fuel was fresh, but purchased at a place I normally don't go to for ethanal free. I questioned how much they sell, and if it was fresh when purchased. (the 661 and 021 run fine on it.)
Now I'm back to operator error, as the saw is still new to me, and I've not settled into a start pattern that works consistently,
and also vapor lock.
High temp of 71° today, so vapor lock should not be an issue.

The neighbor has someone cleaning up their yard tree, but I may go over today or tomorrow and see if there is something to cut on to work the saw in a full cut and longer run time.

I'm an amateur.
I do not fall trees.
I buy semi loads of 100" oak logs, process with a make shift system, and sell 50-70 cords a year.
More cutting than a home owner, but by no means professional.

Everyone here is spot on with the WOT for 5mins or so, when @Stump Shot build me the MK2, we had an extensive conversation about this topic. @awol gave me the same advice for the MK1 build.

After the Feb 2019 update that I think bumped up the fuel curve for both the MK1 and 562 for easier restarts, I am totally guilty of excessive idling. Once I started the saw, I would run it till empty and due to my log formation just being dumped and not nicely stacked, I easily went 2-3mins in idle, few times I have pushed it to the 4minute mark. I specifically did this to test the sluggish response and AT reprogramming the fuel curve, and to my surprise both saws behaved flawlessly, no stumble off idle, or sluggish power. Could I have been lucky with good carbs or was the new software re-tuned on the 1st gen of ATs to be more compatible with the 2nd gen of ATs that went into the MK2 and 572 saws that corrected the earlier mistakes?

Back to the new 562, we also had extensive discussion here on OPE about how the new ATs holds back the saw during break in until a certain amount of time is reached. When this topic came up, I do remember that both the MK1 and 562 ran normal, they were getting stronger through each tank of gas, then powered off the saw, refuel, and suddenly another 20% to 25% gain in power. At the time I did not know what was happening, but now looking back it's all clear. During that same break in, AT is taking in lots of parameters and maybe with it holding back the saw, I do remember that my starts were hit and miss and did not stabilize until I passed the break in period. I remember both saws dying during idle sub 30s, on hot restart the surge followed by a cut off then the saw stumbling during super low RPMs only to die again. It was frustrating for me as I tried to learn the start/re-start sequence only to be back a square one. I would estimate about 8-10 tanks to pass the initial break-in, I never kept notes on my saws, see how the AT behavior changes both in power output and start/re-start sequence.

That made me smile.
Today was good. (Saturday, 06/13/200
Almost all single pull starts.
Did a cord and a good bit of junk wood tossed in the row pack again. That make about a half cord of junk wood this week.
(It's actually all pretty good wood, just a bit short. We will keep it and burn it.)
I've run about a gallon and a half of fuel through the 562. Mixed up fresh today but not into it yet.
I too have not kept notes.

What did the dealer do to the saw?
