Husqvarna 545 autotune starting trouble

I don't remember who originally found the screw, may have been brad or bob, I'm just passing along what I've learned. Can't take credit for that one.
That screw does not show on any ipl, husky or walbro. Walbro hardly acknowledges that the AT carbs exist on their site LOL

It's an adjuster screw and it makes them start good and stuff
Just so there's no misunderstanding... Is this the screw (red circle) that you are talking about?

And this will affect the autotune somehow to "start good and stuff"? Is there any other info available?
Yes, in the red circle is correct. I haven't dissected the carb yet to see exactly where it goes and how it functions, but like any carb you have to have bleeds for different purposes in the carb. The L and H passages are not the only places that allow flowage through the carb.
Not being up to date with my terminology and usual bad with words I'm not going to be the best person to describe it. I get lucky once in a while.

Thanks for all the suggestions everyone.
Overall, I'd like it to start and run a bit easier, but don't think it's bad enough that I'm likely to be looking to return it and replace. Partly I simply haven't had time to really look into it, take it to the dealer, etc... So, I'm not giving up yet.
TK - thanks for all the input! It sounds like I should generally be letting it warm up a bit more before trying to use it, so I'll try that as well. I probably have 10-15 tanks through it at this point, so not a lot, but also not brand new. I might give that screw a try as well one of these days.
One challenge that I have is that I don't think my dealer has dealt with many AT saws, so they're not likely to be as much help as I had hoped. I'll give them another try if needed, but then may simply look for a more knowledgeable dealer to take it to. These guys seemed good at first and they're right around the corner from my house (less than 5min walk!), so that makes them very easy to deal with. We'll see.
First I have to get through another few projects and then will maybe have time to think about the saw a bit more. Building some stairs & a new railing for a 2nd floor deck is on the top of the list for this weekend. Maybe a start on some new flooring as well if I get time. No shortage of things to do in a 200yr old house!

I fired up my 545 prior to removing the muff to send to Brad, and had a little issue with the saw wanting to bog coming off high idle. It was definitely cold natured so I also opened up the "mystery" screw about 1/4 turn as was suggested. TK, I was surprised how easily the screw moved. I also opened my last pail of SEF94 which was about 2 years old, so maybe it's age and volatility may come into question. My Robin weed wacker and BR550 backpack are a little slow to start on the same fuel. At anyrate when the muff comes back I'm trying some fresh 89 non-eth and hoping for success. The all orange and 16" Pro-Lite sure look good together. Hope it runs as good as it's big brother.

I saw no mention of using the air purge bulb? Some call it a primer bulb, but it's not.
My 562xp sure does like a few pumps. :msp_wink:

Ya I left that part out, assumed it was being used. I haven't quite grown out of the assumption stage, some day I'll make it there to the point where nothing is ever assumed :hmm3grin2orange:
I've been toying around with the idea of making a cold start/warm start vid for the 550. I just have no idea how to edit videos and splice two together etc. I'd like to be able to eliminate irrelevant recordings like setting the camera down and other boring stuff, just keep the vid to the meat of it for instructional purposes.

I have an early 562xp AT and had trouble with warm starts. Untill I learn how to start the saw. :msp_rolleyes:
Now it is the easiest starting saw I've ever used...
The bulb works great on the 346xp also!

But you can pop the air filter bracket off and give this little guy a 1/4 turn counterclockwise, that should help.
How easy is it to pop off the air filter bracket? I was looking at it on a 545 at dealer's... Didn't look too easy. Seemed to have stuff connected to it. Not sure what it all was.
Nailed it, Bingo. This is the EXACT starting procedure for my 435. Do it any other way and you'll see that a 435 will tire your arm out too.
Also, I've been lusting for a 545 for awhile and I had new one in my hands today. It feels lighter than my 435! Soon as I get me bonus, I'm gittin one!
