TLTR:msp_razz:
Has anyone else noticed the contradiction in the 562XP manual (it's in the 550XP manual as well)? Y'all did read your manuals, right? :msp_ohmy:
Yet we're instructed to run full out for 3-5 minutes every time we use the saw. And now a dealer is telling a customer to do a full throttle run for 3-5 minutes so the carb can "re-learn". I wonder what dealers and Husqvarna will say when someone brings in a new grenaded AT saw? :msp_confused:
I've had the same problem with mine, and the 550XP as well. I thought it was me, so I'm glad to see somebody else is as incompetent as I am!Zero problems with my 562xp other than the chain brake band sticking to clutch once and awhile when removing bar cover.

.....
What size of tree are u cutting to run WOT for 5 minutes ????
Also, I make sure to run Premium NON-Eethanol gas, I also add Seafoam.

Cut 5 cords so far.....BEAST of a saw for the weight...
Me, if I had one, I am a nerd, I would want to root that sucker anyway.
Seafoam has alcohol in it btw.

Seafoam contains isopropyl alcohol and not ethanol. Big difference between the two, and the amount in SeaFoam is miniscule.I only add 40 ml per gallon Ethanol gas is usually 10 % alcohol. A gallon has 4.5 liters so 40mils per 4500 mils gas is nothing to worry about. Less than1 % with 40ml per gallon.
Isopropyl alcohol is a major ingredient in "gas dryer" fuel additives. In significant quantities, water is a problem in fuel tanks, as it separates from the gasoline, and can freeze in the supply lines at cold temperatures. It does not remove water from gasoline; rather, the alcohol solubilizes water in gasoline. Once soluble, water does not pose the same risk as insoluble water as it will no longer accumulate in the supply lines and freeze. Isopropyl alcohol is often sold in aerosol cans as a windshield de-icer. Isopropyl alcohol is also used to remove brake fluid traces from hydraulic braking systems, so that the brake fluid (usually DOT 3, DOT 4 or mineral oil) does not contaminate the brake pads, which would result in poor braking
Seafoam contains isopropyl alcohol and not ethanol. Big difference between the two, and the amount in SeaFoam is miniscule.
From Wikipedia:
Ethanol is ethyl alcohol...and is VERY similar to isopropyl alcohol.
List of Common and Chemical Names for Alcohols and Ethanol.
I have been running seafoam in my premium non-ethanol gas for years in snowmachines, ice-augers, 2 stroke outboards and haven't blown an engine yet.
But I would NEVER add any alcohol based additive to 10% ethanol gas and use it in a 2-stroke engine....I actually will NOT use 10% ethanol gas in anything except my car or truck and even then I try NOT too.
Ethanol-free gas stations in the U.S. and Canada
For most of us in here E10 is the only option and i have never had a issue with it, but my saws pay my bills so its not sitting around waiting to cut cookies. IMO the ethanol is overhyped
I'm sure all the engineers designing new OPE take ethanol into equasion and the new stuff is more tolarant to ethanol than older equipment.
So I'm having issues with a 2 week old 550xp. Was it doing anything like this?
I'd do the 3-5 minute fix, but I can't get it to stop dying in the cut.
It ran like an absolute champ for 2 days, then all of the sudden started doing this BS.

Mine was acting very similar to that, yes. But only when I first started it, it ran a little better after it had ran for a while. A lot of times, I would have to let it idle, and just slightly blip the throttle for a while to get it to finally start reving. If you tried to rev it normally, it would immediately die. I should have mentioned in my first post, that when I bought the saw, I bought 3 cans of the husky pre-mix to extend the warranty. It ran great on the pre-mix gas, but when I switched to the me-mix gas (91; no ethanol), it started all the problems. But even after switching back to the husky gas, problems remained. After reading the other members comments here, sounds like a better option for you to get the dealer to reset the fuel settings with the diagnostic tool. Since the other members posts, I contacted my dealer again, and asked about the diagnostic tool. Apparently, he doesn't have the tool/software yet. So I think that's probably why he gave me the advise he did. I really think resetting the autotune with the tool is a better route. Then it would run good enough for you to do the tuning run. Just my .02 worth
Exactly what I decided to do when a sprung for the 562 and 550 (plus the ability to extend the warranty out to 4 years). Spending more on saws in the past month than I have in the last 35 years, I wanted to at least give the new toys a fighting chance since they don't get used on a regular basis.I know I have been recommending that small users use the canned premix as cheap insurance for good running and not kill their equipment.
