Had the saw for a week. Starts cold great, will not start when hot and no fuel in the primer bulb. Told vapour lock / heat soak. Back at the shop so we will see. I understand this is a known issue. If it can't be resolved what would you recommend as a comparable saw ( hoping it won't come to that as it is awesome when it runs !! )

I also have the 562xp. Its new and I haven't had any issues with it regarding a hot start. Last week I did a 33in tree and ran the saw for hours. I never ran the saw out of fuel while opening it. I make sure of that, at most it was 2 pulls to restart. I'd check to make sure that your not over tightening the fuel cap

Thanks for the info. I have about 4 tanks of fuel through it. Starts cold great. It has been hot here and no matter what I did or dealer did it wouldn't start. Did open the cap and didn't over tighten. The serial number says its a 2017 model which surprised me. Maybe if I'm lucky they will swap it out for a 572xp.

If it goes back to the shop for a second time I won't be owning it anymore, that's for sure.

This guy had the same issue, resolved it with making an opening on the cover for warmer weather.

I believe my saw has that hole in the cover from the manufacturer. If it wasn't in the shop I could check ;)
Thanks for the link, I have read most posts but missed that one and its current.

Both my 439& 562 if they don't want to start when hot , I hold the throttle wide open and they go first pull.( be careful as this can be a little dangerous.)

I remember being told somewhere in the past that when hot, one should not use the decompression button. I do that and I think it helps when hot starting.

Correct, No decomp when warm. All that's in the manual. It is a new saw but a 2017 build. Would be interested to hear what updates the saw received until 2020.
Spoke to one dealer who advised that it isn't a warranty issue, he also said no one should use a saw between March and November or receive a 10k fine.
Apparently a good saw guy according to the father in law but maybe the heat is getting to him.

They are going to run the diagnostic tool on it and we had a chat about the 572xp and what was done to it ( heat shield and insulting foam ). Anyone have an idea of dealer cost for a 572xp as that will be what I propose if it cant be fixed. List is between $989 and$1160 CDN for the 2019/2020 model.

if starting with the throttle wide open.. it best to do it on the ground and have your helper hold the throttle open.. .. saves on a trip to urgent care or ER
Why not just use the chain brake?

Sometimes starting a hot soul with the brake on is even difficult
Weird. I guess my saws are all easy starters then. I try to remember to engage the brake before starting just to prevent any accidents, but I usually don't start with any throttle, except for my Stihl MS-150-TC which has a high idle function. My Husky 460 has a high idle on cold starts and will move the chain if the brake isn't engaged. Haven't noticed it on hot starts.

Update: diagnostics says running too lean so new carb ordered as per Husqvarna tech. Can't remember which one but I believe its replacing an EL44.

Yes and I think they are trying to educate themselves a little more. They reached out to Husqvarna directly which was appreciated.

I have been working on a 562xp with same problem. My 550xp does the same thing. It has to do with the cylinder leaning back towards the carburetor and heat soaking. Accord to the stick on my 550, the say to set the choke and turn it off (not pulling the throttle trigger), push decompression button, prime 6 times then pull the cord. It's a 50/50 shot if it works. I think they have them running a little on the lean side causing them to build up extra heat.

Are there any folks that "tune" or modify the Husky auto tune system?

Not that I'm aware of. Not to the computer software anyways. I know of people that have adjusted pop off pressure and made some modifications on the throttle blade. But I think those mods were for the hesitation issues of the 562xp

According to the manual which is same for 550 and 562 , no decomp on warm start. Found out the temp was 113 on the diagnostic and think I read somewhere that is high ( around 85 norm ??) feel free to correct.

I I recall correctly the carb was updated last year to rectify the hot start issue. That may be your problem with a 2017 saw.
