I had an older husky 550 that wanted to die when you let off the throttle sometimes. I pulled the carb and adjusted the “hidden” screw and it was much better, also found my auto tune saws ran much better on 87 mixed 50:1 than they did on 92 at 40:1. Not sure if jreds are the same or not.So I got the j red running again but it still won't idle. Uncle says he's done messing with it. So the saws getting replaced. Options are the 261 v2 and the cs501p. The echo is about $100 cheaper and a little lighter. The stihl is a little stronger and m tronic. I feel like any saw forum will lean hard to the stihl but figured I'd ask.
I ask about that screw under the brass plug and was told don't touch it. I could try a gallon of fuel at 50:1 and see what happens. I run everything on 40:1 and 92 so maybe that would help.I had an older husky 550 that wanted to die when you let off the throttle sometimes.

That's the one, who told you not to touch it.View attachment 658620 I ask about that screw under the brass plug and was told don't touch it. I could try a gallon of fuel at 50:1 and see what happens. I run everything on 40:1 and 92 so maybe that would help.
Yes, all I run 40:1 on my AT saws as well as my stihl mtronic saws.You run AT Huskys @ 40:1?

So the manufacturer of a chainsaw says to use 50:1, the premix gas that has their name on it is 50:1, the AT saws aren't "tunable" and were designed to run 50:1, but you put 40:1 in them? How do they run? I mean do they run fine?Yes, all I run 40:1 on my AT saws as well as my stihl mtronic saws.
Since I've acquired more ported saws I didn't want to have a couple different mixes around so I just tuned all my saws with screws to 40:1, the mtronic and AT saws take care of themselves.
It was someone on O P E that told me not to touch it. I've read a few times that it can help with idle problems.That's the one, who told you not to touch it.

I would need to understand the situation regarding scrounging in your area a little better in order to give and answer. 45 min seems a bit far to get wood to me, but in your local that may be different. Do you have any local tree services around that need a spot to drop wood off, or have a yard they need cleaned up. Craigslist often had free wood as does Facebook(you'll have to search a bit to get the good ones most likely).Opinion poll:
Former landlord/friend sells solar jobs, occasionally sets me up with wood or some light tree cutting that results in free wood. Have not dealt with him in the last year or so due to me feeling like I was being taken advantage of/being put in shady situations.
Has a job site 45+ mins away from me where the installation is completed but the tree service hired left the wood behind. 45 min trip is based on driving the toll highway nearly directly there, and will not be an option for the return trip when loaded down with wood. I work Mon-Weds; I am off Thurs-Sunday but that's when I am on daddy duty with my son and at 2.5 months old, he is not big enough to make the trip to get firewood with dad- so I would have to ask my mother to babysit. From his poor photos texted to me, it looks to be about 4-5 different stacks of wood, each one roughly what I could carry in one trip with my truck and converted boat trailer. Appears to be 90-95% oak, all green, cut in various lengths (typical tree service stuff) and ranging from maybe 20-22" in diameter and down.
I currently have enough wood for this coming winter, but have slacked off a bit and have nothing in the pipe for 2019-2020. Have son at home and two boats that I have been spending my time with instead of chainsaws. New oil boiler going in this fall to replace the 32yo unit original to my house, so oil consumption will be improving drastically...as well as new insulation going in my crawlspace today. I have a few other sources for wood locally, but nothing that is calling me and practically begging me to come pick the wood up...
So my questions/thoughts/options are:
1. Make a trip down with truck and trailer, ***** situation myself and decide if more trips are worth the time, take full load back? At roughly 90 minutes round trip, and my Frontier and smallish trailer only able to carry about 1-1.25 cords a trip.
2. Talk a buddy into taking the drive down with me (with his truck/trailer) at the cost of some wood/beer to try to get it all in one trip. This costs me some wood, but saves time and effort and helps the former landlord/friend out the most.
3. Tell landlord/friend that I will come and get it, but he needs to pay me in gas money and beer for helping him out, and I will be on my own schedule so I might only make one trip per week. I have to take into account the time spent unloading and stacking at my house too, you know. And its in the upper 80s out...
4. Tell landlord/friend that I am just too swamped and can't help him out, but if the tree service could deliver or he could rent a truck of his own, I am happy to provide a place for them/him to dump the wood.
Thoughts?
I ran 50:1 for many years without a single problem the only reason I switched was the recommendation of the builders of my ported saws. The only problem I've ever had with mix is running 50:none .I know not everyone agrees and I don’t want to start an oil thread, lol. But switching to 50:1 with 87 gas really made a big differance with my auto tune saws. Ran much better, no more bog, hot start issues, more power. Stock saws don’t have enough compression to gain anything from 92 IMO.
As far as adjusting the screw- “550xp was giving me a little trouble, it was having an off idle bog/ slow throttle response, and would die if left to idle for longer than 30 seconds. Then required several pulls of the rope to bring it back to life, almost like it was flooding itself. Needless to say I was a little disappointed in the performance. If this was a normal carburetor most people would just lean in the l screw and go from there, but this being an autotune there are no screws to turn... Or are there. http://************/threads/husqvarna-550xp-carb-fix.1524/data/attachments/13/13817-30f6ad68b07f9e06488c1ac8e415ad03.jpgthis little guy is hiding behind a brass plug masquerading as an accelerator pump.
I remembered reading a thread on Another Site about this little guy, it was never really cleared up to me where it went or what it's for, if someone else knows please chime in for all of our benefit. Anyway it was suggested that this screw be turned 1/4 turn CCW and that is what I did.
After reassembling I took it out and did some cuts and got it warmed up to operating temps then let it idle for several minutes without issue, it didn't die once. It also had throttle response you would expect out of a pro grade 50cc saw. I then let it set for a short while +/- 10 minutes and it started one pull low idle. In my lowly opinion this has fixed my problem.“ From the O P E forum.
