brand new Husqvarna 545 - bog after idle

[seasalt]

Newbie on the site here, but love all the great info here...
I very recently purchased a Husqvarna 545 that the throttle bogs somewhat after idle. My old 42 Special was having issues and it was too expensive to have fixed so I decided to splurge for a new saw. Who doesn't love a new toy?!
I have about six tanks of gas through it. I took it back to the dealer who found no error codes and consulted Husqvarna who said it is normal ( or not abnormal) and that the saw requires about 20 hours to break in before they will do something. It will realistically take me a year or more to put 20 hours on it as I mostly use at my cabin. I am not new to saws, having owned and worked with several Husky's but I am completely new to " auto tune" on saws. I have attached a small video. The bog isn't always this bad but I find it fairly annoying and difficult to believe it is normal. As well, it has stalled a few times when I hit the throttle. I am thinking a carb that is not quite right. The dealer was helpful and did reach out to Husqvarna who holds the warranty card .
I have since repaired the 42 Special myself and it is instantly responsive, so I now have a great 27 year old saw and a brand new one that does not run as well upon hitting the throttle.
Any thoughts or suggestions would be appreciated. Is this normal? Thanks!

I couldn't view your video with my phone. Is it a 545 mark 2 or the previous version 545? I have the previous version and I really like it. It does bog off idle if I don't start it with the fast idle engaged and let it run a couple seconds.

A little odd both saws had the same problem initially, I hope the fuel mix is fresh and mixed properly? it looks like this isn't you're first rodeo so I assume it is.

No this is not normal! it's also been a common problem with the early AT saws. Husqvarna's explanation is not acceptable and a flat out false, 20 hours for it to run correctly? that is total BS again not acceptable. The first thing the dealer should have done is update the firmware, this helps some saws with this problem. If that doesn't help a pressure/vacuum test is in order, these saws are known to leak. That said I've had to deal with a few of these saws and I even modded the carbs to try and get then to work, which did work sometimes. In the end most of the time a new carb is the only way to fix the problem for good. I really can't believe Husqvarna is still so incompetent, that or they're still just trying to wiggle out warranty work.

Hope this was of some help.

Good point, does the saw stop doing this when it warms up? if so that is in fact normal. The saw is a Mark 1 model.

Mine does it if you start it and then immediately hit the throttle. It will bog and sometimes stall out. It says in the manual to start it in fast idle EVERY time, cold or hot. If I do that it runs perfectly and is an amazing little saw. If cold I have to let it warm up about 30 seconds, if warm just a few seconds. It is hard to get used to after using an older regular carb saw and then picking this one up. I think mine is a 2016 model but I just bought it NIB earlier this year. Only has 5 maybe 7 tanks through it.

a lot of saws will do that when cold, just like cars did back in the day. I doubt that's the issue here though, these saw are notorious for doing this, and Husky has had a hard time dealing with it appropriately.

I had heard they had solved all these problems with the mark 2 model. That's why I asked the op which version he had.

I believe they did solve the problem with the MK2.

Thanks for the relies so far! It is the first version, not the Mark II. Firmware was updated at purchase and I am using fresh Husqvarna pre-mix fuel so I could get the additional warranty(LOL!). I do part it it high idle cold and let it run a minute before hitting the throttle, although I did not do it when hot.
The dealer was able to replicate the issue. It does it cold and hot.

OK have the dealer vacuum/pressure test it, if it passes, a new carb will almost certainly fix the problem.[emoji111]

He should resolve issue, or hand you a new saw.

Wanna sell that 42 special?

LOL, I have kind of grown fond of it over the years ...

This dealer interaction is exactly what killed off many Husky clientele. Have a real genuine problem, your dealer can't help but agree with you because its clearly there but he has no idea how to fix it, he goes to Husky corporate for help & gets told 'nothing to see here folks' this is normal and gives you the rubbish break-in excuse. I'd re-calibrate the saw on an oxygen rich cold day, sure do a pressure vac test but that don't seem like an air leak. Then get into the carb first see if that brass adjustment screw is there like the 550's had, then consider notching the throttle plate a little bit at a time to see if it disappears. Essentially its a lean off idle bog that would normally be fixed by richening the L-speed a 1/4 of a turn. Break in will lessen things up allowing for faster spool up but on a conventional saw 10 seconds with a screwdriver in hand would resolve this.

I agree!!

With the model carb that saw has those fixes don't seen to work anymore, they did on the early 562's and some of the 550's. After talking with Bob and a few others it's actually a rich condition, that adjustment screw on the 550 is a bleed screw not exactly a jet.

Besides all that it's a new saw, it needs to be fixed or replaced, which seems like a challenge with Husqvarna these days, well unless you have a dealer that knows what's going on.

Yeah I really like my V-1 2014 550xp, don't use it a too much but it spools up in an instant, would gos as far as saying it goes from idle to WOT out of wood faster than any saw I own. So these saws can run right...they should run right & if Husky can't garuantee this they should stop selling them. They know very well whats going on here. And yes it appears the mkII saws are without issue, but they can't keep treating folks like fools, its bad business. Either find a solution for the old model or get them the $%&@ off the shelf I say.

I don’t know anything about the 545.....but.....if I bought a brand new saw from the dealer and it had an off idle bog I’d be pissed. Cold is one thing, but if it did once hot the dealer better be helping me get it resolved.

Thanks for the replies...Guess it is time to be a squeaky wheel!
